The square yard (Northern India: gaj , Pakistan: gaz) is an imperial unit and U.S. customary unit of area. It is in widespread use in most of the English-speaking world, particularly the United States, United Kingdom, Canada, Pakistan and India. It is defined as the area of a square with sides of one yard (three feet, thirty-six inches, 0.9144 metres) in length.
There is no universally agreed symbol but the following are used:
One square yard is equivalent to:
The acre is a unit of land area used in the imperial and US customary systems. It is traditionally defined as the area of one chain by one furlong, which is exactly equal to 10 square chains, 1⁄640 of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the international yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres. The acre is sometimes abbreviated ac, but is usually spelled out as the word "acre".
A furlong is a measure of distance in imperial units and United States customary units equal to one eighth of a mile, equivalent to 660 feet, 220 yards, 40 rods, 10 chains or approximately 201 metres. It is now almost obsolete, except in horse racing, where in many countries it is the standard measurement of race lengths.
The imperial system of units, imperial system or imperial units is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
The Claymore mine is a directional anti-personnel mine developed for the United States Armed Forces. Its inventor, Norman MacLeod, named the mine after a large medieval Scottish sword. Unlike a conventional land mine, the Claymore is command-detonated and directional, meaning it is fired by remote-control and shoots a wide pattern of metal balls into the kill zone. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations.
The square metre or square meter is the SI derived unit of area with symbol m2. It is the area of a square with sides one metre in length.
The square mile is an imperial and US unit of measure for area. One square mile is an area equal to the area of a square with sides of length one mile.
A cubic yard is an Imperial / U.S. customary unit of volume, used in Canada and the United States. It is defined as the volume of a cube with sides of 1 yard in length.
The rod, perch, or pole is a surveyor's tool and unit of length of various historical definitions, often between approximately 3 and 8 meters. In modern US customary units it is defined as 16+1⁄2 US survey feet, equal to exactly 1⁄320 of a surveyor's mile, or a quarter of a surveyor's chain, and is approximately 5.0292 meters. The rod is useful as a unit of length because whole number multiples of it can form one acre of square measure (area). The 'perfect acre' is a rectangular area of 43,560 square feet, bounded by sides 660 feet long and 66 feet wide or, equivalently, 40 rods and 4 rods. An acre is therefore 160 square rods or 10 square chains.
The square foot is an imperial unit and U.S. customary unit of area, used mainly in the United States and partially in Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong. It is defined as the area of a square with sides of 1 foot.
A system of measurement is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Systems of measurement in use include the International System of Units or SI, the British imperial system, and the United States customary system.
A square inch is a unit of area, equal to the area of a square with sides of one inch. The following symbols are used to denote square inches:
A football pitch is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour.
The bigha is a traditional unit of measurement of area of a land, commonly used in India, Bangladesh and Nepal. There is no "standard" size of bigha. The size of a bigha varies considerably from place to place. The size of Bigha is different in different areas.
A guz or the Mughal yard is a unit of length used in parts of Asia. Historically, it was a regionally variable measurement similar to the English yard both in size and in that it was often used for measuring textiles. Values of the guz ranged from 24 to 41 inches over time. Today, it is generally used in the Indian subcontinent as the word for a yard. A present day sari is still measured as 7 guz while a traditional one can be as long as 9 guz.
A marla is a unit of area used in the Indian subcontinent.
A cricket field is a large grass field on which the game of cricket is played. Although generally oval in shape, there is a wide variety within this: some are almost perfect circles, some elongated ovals and some entirely irregular shapes with little or no symmetry – but they will have entirely curved boundaries, almost without exception. There are no fixed dimensions for the field but its diameter usually varies between 450 feet (137 m) and 500 feet (150 m) for men's cricket, and between 360 feet (110 m) and 420 feet (130 m) for women's cricket. Cricket is unusual among major sports in that there is no official rule for a fixed-shape ground for professional games. On most grounds, a rope demarcates the perimeter of the field and is known as the boundary.
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.
The gunta or guntha is a South Asian measure of area. This unit is typically used to measure the size of a piece of land.
The following are the basic measurements of land used in the Punjab region, divided between Indian and Pakistani Punjab and many parts of North India and Pakistan in ascending order.
