The Carolingian pound (Latin : pondus Caroli, German : Karlspfund), also called Charlemagne's pound or the Charlemagne pound, was a unit of weight that emerged during the reign of Charlemagne. It served both as a trading weight and a coinage weight. It had a mass of about 408 g and was introduced in as part of Charlemagne's monetary reform around AD 793/94. This stipulated that 240 denarii (= pfennigs) were to be minted from one pound weight of silver.
The units of weight that emerged over time as a result of the Carolingian monetary system and its associated pound or Karlspfund, were of great importance for large parts of Europe. The basic features of this monetary system, which was based on the Carolingian pound, continued to exist in England until 1971. Initially, the Carolingian pound was valid across the whole of the Carolingian Empire and, to a lesser extent, in the Holy Roman Empire under the Ottonian dynasty that followed. Under the Salians, who ruled from 1024, the Cologne Mark was introduced. This amounted to 576 thousandths of the Carolingian pound and became the dominant coinage weight. Similar modifications were made to trading weights at the same time.
The Karlspfund is first attested by a contemporary manuscript, [1] as well as reports from the Council of Frankfurt in 794. These say that new coins, new deniers or denars, were now to be minted in the Empire. These deniers later became known as pfennigs . The exact derivation of the target weight of the Charlemagne pound itself has yet to be clarified.
Today, the original weight of the Charlemagne pound can be determined primarily by weighing surviving Carolingian coins from the early period, although a variation of several per cent occurs. In the literature, the Karlspfund is often given 408.25 g or approximately as 408 g, [2] The latter is the equivalent of one denier of exactly 1.7 g in weight.
From the middle of the 12th century, several variants of the Carolingian pound emerged in France which were legal tender at different times.
The English pound weight, which was adopted very early and directly from France, shows that the value of the Carolingian pound was a little lower in France for a long time.
The weight of the livre des poids-de-marc also corresponds very closely to one seventieth of the mass of a French cubic foot of water. So it is likely that this is why there was a slight increase in the weight measure in France. The ratio of the two is about 3136 : 3125, so only there is only a +0.35% difference.
Pound | Ratio | Numerical values | 3136 : 3125 | Empirical values |
---|---|---|---|---|
Livre de Troyes | 6 : 5 | 487.71072 g | ≈ 489.43 g | c. 489.5 g |
Libra parisi | 9 : 8 | 457.22880 g | ≈ 458.84 g | c. 459.0 g |
Carolingian pound(Karlspfund) | 1 : 1 | 406.42560 g | ≈ 407.86 g | c. 408.0 g |
Livre tournois | 9 : 10 | 365.78304 g | ≈ 367.07 g | c. 367.0 g |
The English system of Troy weights probably originates in the French market town of Troyes where English merchants traded at least as early as the early 9th century. [3] [4] The name troy is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Earl of Derby. [3] [5] The English weights were based on the older value of the livre de Troyes which was 12⁄10 of the Carolingian pound. Thus it is easy to compare them directly to the Karlspfund:
Pound | Ratio | Numerical values | Official values (1958) [lower-alpha 1] |
---|---|---|---|
London | 225 : 196 | 466.5600 g | g | 466.55215200
Avoirdupois | 125 : 112 | 453.6000 g | g | 453.59237000
Merchant | 625 : 448 | 437.4000 g | g | 437.39264250
Carolingian pound(Karlspfund) | : 1 | 1406.4256 g | (406.41876352 g) |
Troy | : 49 | 45373.2480 g | g | 373.24172160
Tower | 675 : 784 | 349.9200 g | g | 349.91411400
The metrological numerical values only differed from their official values (1958) by about 0.0017 %. The former corresponded to an English grain of exactly 64.8 mg.
Many of the important weights in the German Holy Roman Empire, such as the Vienna pound, the Cologne mark and the Nuremberg apothecary's pound were derived from the Charlemagne pound. For example, the ratio of the Cologne mark to the Karlspfund is exactly 576:1000.

The Karlspfund weighed 500 gold grains (later version), or 8,000 corn grains. |
The relatively large deviation of the empirical Karlspfund of almost 0.4% - which is still within the coefficient of variation determined for old weights is due to the later French, slightly larger version.
The so-called Custom Union mark of the German Customs Union was set at 233.8555 g in 1838, i.e. only around 0.105% less than its numerical value. Cologne and Vienna marks maintained their ratio of 10 : 12. Thus in creating their derivatives, the leading metrologists of the Holy Roman Empire preserved the Carolingian pound with outstanding precision for over a thousand years.
After the Carolingian monetary reform, the schilling (lat. solidus) was initially only a coin of account, the unminted gold equivalent of 12 silver denarii (denarius = pfennig). A schilling was the equivalent of 1/20th of a Carolingian pound in silver weight. At 12 pfennigs to the schilling, Carolingian silver pfennigs were actually minted from a pound of silver 240.
For historical units of length, the coefficient of variation is generally accurate to within ± 0.2%. In ancient and medieval units of weight, a range of about (1.0023 −1) = 3/500 can be used. The ratio 126 : 125 and its reciprocal value represents the higher metrological precision requirements of medieval weights.
Coefficients of variation become considerably smaller from around the Renaissance period. In addition, a distinction must be made between the actual and known values of the dimensions themselves and the tolerances that inevitably occur in "mass production". At that time, purely for technical reasons, the variation was no better than, for a pfennig, 1.6 to 1.8 g.

The weight given for the Carolingian pound varies slightly in the literature for the following reasons:
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.45359237 kilograms, and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm, #, and ℔ or ″̶.
The shilling is a historical coin, and the name of a unit of modern currencies formerly used in the United Kingdom, Australia, New Zealand, other British Commonwealth countries and Ireland, where they were generally equivalent to 12 pence or one-twentieth of a pound before being phased out during the 1960s and 1970s.
A penny is a coin or a unit of currency in various countries. Borrowed from the Carolingian denarius, it is usually the smallest denomination within a currency system. At present, it is the formal name of the British penny (abbr. p) and the de facto name of the American one-cent coin (abbr. ¢) as well as the informal Irish designation of the 1 euro cent coin (abbr. c). Due to inflation, pennies have lost virtually all their purchasing power and are often viewed as an expensive burden to merchants, banks, government mints and the public in general.
Troy weight is a system of units of mass that originated in the Kingdom of England in the 15th century and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight, the troy ounce, and the troy pound. The troy grain is equal to the grain unit of the avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. One troy ounce equals exactly 31.1034768 grams.
The English penny, originally a coin of 1.3 to 1.5 grams pure silver, was introduced c. 785 by King Offa of Mercia. These coins were similar in size and weight to the continental deniers of the period and to the Anglo-Saxon sceats which had preceded it.
The franc, also commonly distinguished as the French franc (FF), was a currency of France. Between 1360 and 1641, it was the name of coins worth 1 livre tournois and it remained in common parlance as a term for this amount of money. It was reintroduced in 1795. After two centuries of inflation, it was redenominated in 1960, with each new franc (NF) being worth 100 old francs. The NF designation was continued for a few years before the currency returned to being simply the franc. Many French residents, though, continued to quote prices of especially expensive items in terms of the old franc, up to and even after the introduction of the euro in 2002. The French franc was a commonly held international reserve currency of reference in the 19th and 20th centuries. Between 1998 and 2002, the conversion of francs to euros was carried out at a rate of 6.55957 francs to 1 euro.
The livre tournois was one of numerous currencies used in medieval France, and a unit of account used in early modern France.
£sd, spoken as "pounds, shillings and pence", is the popular name for the pre-decimal currencies once common throughout Europe. The abbreviation originates from the Latin currency denominations librae, solidi, and denarii. In the United Kingdom, these were referred to as pounds, shillings, and pence.
The pfennig ; symbol pf or ₰) or penny is a former German coin or note, which was the official currency from the 9th century until the introduction of the euro in 2002. While a valuable coin during the Middle Ages, it lost its value through the years and was the minor coin of the Mark currencies in the German Reich, West Germany and East Germany, and the reunified Germany until the introduction of the euro. Pfennig was also the name of the subunit of the Danzig mark (1922–1923) and the Danzig gulden (1923–1939) in the Free City of Danzig.
Groschen is the name for various coins, especially a silver coin used in parts of Europe including France, some of the Italian states, England, and various states of the Holy Roman Empire.
The denier or penny was a medieval coin which takes its name from the Frankish coin first issued in the late seventh century; in English it is sometimes referred to as a silver penny. Its appearance represents the end of gold coinage, which, at the start of Frankish rule, had either been Roman (Byzantine) or "pseudo-imperial". Silver would be the basis for Frankish coinage from then on. The denier was minted in France, Cyprus and parts of the Italian peninsula for the whole of the Middle Ages, in states such as the patriarchate of Aquileia, the Kingdom of Sicily, the Republic of Genoa, the Republic of Siena, Kingdom of Cyprus, and the crusader state Kingdom of Jerusalem, among others.
The Reichsthaler, or more specifically the Reichsthaler specie, was a standard thaler silver coin introduced by the Holy Roman Empire in 1566 for use in all German states, minted in various versions for the next 300 years, and containing 25–26 grams fine silver.
The Hamburg Mark refers to two distinct currencies issued in the city of Hamburg until 1875:
The livre was the currency of Kingdom of France and its predecessor states of Francia and West Francia from 781 to 1794. Several different livres existed, some concurrently. The livre was the name of coins and of units of account.
The livre parisis, also known as the Paris or Parisian livre, was a medieval French coin and unit of account originally notionally equivalent to a French pound of silver. It was the chief currency of the Capetian dynasty before being generally replaced by the livre tournois under Philip II in the 13th century. Louis IX ceased minting it and it was finally abolished as a unit of account by Louis XIV in 1667.
The traditional French units of measurement prior to metrication were established under Charlemagne during the Carolingian Renaissance. Based on contemporary Byzantine and ancient Roman measures, the system established some consistency across his empire but, after his death, the empire fragmented and subsequent rulers and various localities introduced their own variants. Some of Charlemagne's units, such as the king's foot remained virtually unchanged for about a thousand years, while others important to commerce—such as the French ell used for cloth and the French pound used for amounts—varied dramatically from locality to locality. By the 18th century, the number of units of measure had grown to the extent that it was almost impossible to keep track of them and one of the major legacies of the French Revolution was the dramatic rationalization of measures as the new metric system. The change was extremely unpopular, however, and a metricized version of the traditional units—the mesures usuelles—had to be brought back into use for several decades.
The Sachsenpfennig, sometimes called the Wendenpfennig or the Hochrandpfennig, was a well-known coin of the pfennig type minted in the eastern part of the Stem Duchy of Saxony during the 10th and 11th centuries. It had an upturned perimeter and, next to the Otto Adelheid Pfennig was the most common pfennig type of its time. Sachsenpfennigs are the oldest coins minted in Saxony. Its different names represent a lack of clarity within mediaeval numismatics about the coin.
A Münzfuß is an historical term, used especially in the Holy Roman Empire, for an official minting or coinage standard that determines how many coins of a given type were to be struck from a specified unit of weight of precious metal. The Münzfuß, or Fuß ("foot") for short in numismatics, determined a coin's fineness, i.e. how much of a precious metal it would contain. Mintmaster Julian Eberhard Volckmar Claus defined the standard in his 1753 work, Kurzgefaßte Anleitung zum Probieren und Münzen, as follows: "The appropriate proportion of metals and the weight of the coin, measured according to their internal and external worth, or determined according to their quality, additives and fineness, number and weight, is called the Münzfuß."
The schilling was the name of a coin in various historical European states and which gave its name to the English shilling. The schilling was a former currency in many of the German-speaking states of the Holy Roman Empire, including the Hanseatic city states of Hamburg and Lübeck, the March of Brandenburg, and the Duchies of Bavaria, Mecklenburg, and Württemberg. It was also used in Switzerland and in Austria, where silver schillings were introduced as recently as 1923.
The Carolingian monetary system, also called the Carolingian coinage system or just the Carolingian system, was a currency structure introduced by Charlemagne in the late 8th century as part of a major reform, the effects of which subsequently dominated much of Europe, including Britain, for centuries. It is characterised by having three denominations with values in the ratio 1:20:240, the units of which went under different names in the different languages, but which corresponded to the Latin terms libra (pound), solidus (shilling) and denarius (penny), respectively.
