Miles per hour (abbreviated mph, MPH or mi/h) is an imperial and United States customary unit of speed expressing the number of statute miles covered in one hour. It is used in the United States, United Kingdom and some Commonwealth nations, notably in the Caribbean region.
The system of imperial units or the imperial system is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The Imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, although some imperial units are still used in the United Kingdom, Canada and other countries formerly part of the British Empire. The imperial system developed from what were first known as English units, as did the related system of United States customary units.
In everyday use and in kinematics, the speed of an object is the magnitude of its velocity ; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
An hour is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions.
Speed limits and road traffic speeds are given in miles per hour in the following jurisdictions (elsewhere kilometers per hour are used):
The British Virgin Islands (BVI), officially simply the Virgin Islands, are a British Overseas Territory in the Caribbean, to the east of Puerto Rico. The islands are geographically part of the Virgin Islands archipelago and are located in the Leeward Islands of the Lesser Antilles.
The Cayman Islands is an autonomous British Overseas Territory in the western Caribbean Sea. The 264-square-kilometre (102-square-mile) territory comprises the three islands of Grand Cayman, Cayman Brac and Little Cayman, which are located to the south of Cuba and northeast of Honduras, between Jamaica and the Yucatán Peninsula. As of spring 2018, the total population of the Cayman Islands is estimated to be 64,420 making it the second-most populated British overseas territory after Bermuda. The capital city is George Town, situated on Grand Cayman, by far the most populous of the three islands.
The Falkland Islands is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about 300 miles east of South America's southern Patagonian coast, and about 752 miles from the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of 4,700 square miles, comprises East Falkland, West Falkland and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, and the United Kingdom takes responsibility for their defence and foreign affairs. The Falkland Islands' capital is Stanley on East Falkland.

Road traffic speeds in other countries are indicated in kilometres per hour.
Miles per hour is the unit also used in the Canadian rail system,which uses km/h on roads.
Nautical and aeronautical applications favour the knot as a common unit of speed. (One knot is one nautical mile per hour, with a nautical mile being exactly 1,852 meters or about 6,076 feet.)
In some countries mph may be used to express the speed of delivery of a ball in sporting events such as cricket, tennis and baseball.

Pendolino is an Italian family of tilting trains used in Italy, Spain, Poland, Portugal, Slovenia, Finland, Russian Federation, the Czech Republic, the United Kingdom, Slovakia, Switzerland and China. Based on the design of the Italian ETR 401 and the British Advanced Passenger Train, it was further developed and manufactured by Fiat Ferroviaria, which was taken over by Alstom in 2000.
A Neighborhood Electric Vehicle (NEV) is a U.S. denomination for battery electric vehicles that are usually built to have a top speed of 25 miles per hour (40 km/h), and have a maximum loaded weight of 3,000 lb (1,400 kg). Depending on the particular laws of the state, they are legally limited to roads with posted speed limits of 45 miles per hour (72 km/h) or less. NEVs fall under the United States Department of Transportation classification for low-speed vehicles. The non-electric version of the neighborhood electric vehicle is the motorised quadricycle.
Hurricane Marilyn was the most powerful hurricane to strike the Virgin Islands since Hurricane Hugo of 1989, and the third such tropical cyclone in roughly a two-week time span to strike or impact the Leeward Islands, the others being Hurricane Iris and the much more powerful and destructive Hurricane Luis. The thirteenth named storm, seventh hurricane and third major hurricane of the extremely active 1995 Atlantic hurricane season, Marilyn formed on September 12 as a tropical depression from a tropical wave that moved off the coast of Africa on September 7. After formation, the storm quickly became a tropical storm, and steadily intensified into a hurricane by the time it struck the Lesser Antilles on September 14 at Category 1 strength. Entering the northeastern Caribbean Sea, rapid intensification ensued and it peaked on September 16 north of Puerto Rico as a Category 3 hurricane shortly after it had impacted the U.S. Virgin Islands. A Hurricane Hunter reconnaissance flight reported hail, which is unusual for tropical cyclones. After heading north past Bermuda, Marilyn weakened and became extratropical on September 22. The remnant circulation wandered the Atlantic Ocean from September 23 – October 1, just south of Nova Scotia.
Determination of the fastest rail vehicle in the world varies depending on the definition of "rail".
Speed limits in the United States are set by each state or territory. States have also allowed counties and municipalities, to enact typically lower limits. Highway speed limits can range from an urban low of 25 mph (40 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h). Some states have lower limits for trucks and at night, and occasionally there are minimum speed limits.
Plans for high-speed rail in the United States date back to the High Speed Ground Transportation Act of 1965. Various state and federal proposals have followed. Despite being one of the world's first countries to get high-speed trains, it failed to spread. Definitions of what constitutes high-speed rail vary, including a range of speeds over 110 miles per hour (180 km/h) and dedicated rail lines. Inter-city rail in the United States with top speeds of 90 miles per hour (140 km/h) or more but below 125 mph (201 km/h) is sometimes referred to as higher-speed rail.
The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance travelled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden acceleration and heavy braking waste energy.
Cyclone Olaf was the sixth cyclone to form in the Southwest Pacific Ocean during the 2004–05 South Pacific cyclone season. Olaf was also one of three simultaneous cyclones to form during the 2004–05 season, forming 21 hours after Cyclone Nancy formed to the east. A powerful Category 5 cyclone, Olaf stuck American Samoa causing heavy damage although exact estimates are unknown. Despite the damage, there were no reported deaths or injuries from the cyclone. Olaf was third South Pacific cyclone to hit the Cook Islands during the 2004–05 season, and Cyclone Percy would later affect the already devastated archipelago less than 2 weeks later.
The V150 was a specially configured TGV high-speed train notable for breaking the world land speed record for conventional railed trains on 3 April 2007. The train was built in France and reached a speed of 574.8 kilometres per hour (357.2 mph) on an unopened section of the LGV Est between Strasbourg and Paris, in France topping the previous record of 515.3 kilometres per hour (320.2 mph) set in 1990.

The climate of Iceland is subarctic near the southern coastal area and tundra inland in the highlands. The island lies in the path of the North Atlantic Current, which makes its climate more temperate than would be expected for its latitude just south of the Arctic Circle. This effect is aided by the Irminger Current, which also helps to moderate the island's temperature. The weather in Iceland is notoriously variable.
Tropical Storm Cindy was a weak but unusually wet Atlantic tropical cyclone that caused disastrous floods and mudslides across Martinique in August 1993. Cindy formed east of the island and became the annual hurricane season's third named storm on August 14. Due to unfavorable atmospheric conditions, Cindy remained disorganized throughout its journey across the northeastern Caribbean Sea. After attaining maximum sustained winds of 45 mph (75 km/h), the storm began to weaken from an interaction with the high terrain of Hispaniola. It made landfall in the Dominican Republic as a tropical depression on August 16, and dissipated over the territory the following day.
Canadian speed limits are set by different levels of government, depending on the jurisdiction under which the road falls, resulting in differences from province to province. The limits have been posted in kilometres per hour (km/h) since September 1, 1977. Before then, when Canada used Imperial units, speed limits were in miles per hour (mph).
The kilometre per hour is a unit of speed, expressing the number of kilometres travelled in one hour.
Typhoon Melor, known in the Philippines as Typhoon Quedan, was the second category 5 typhoon in 2009. It interacted with Typhoon Parma in the first week of October southeast of Taiwan.

The Energica Ego is an electric sport motorcycle. It is claimed by Energica to be the world's first street-legal electric Italian sport motorcycle. The prototype finished in 2013 and the vehicle came into market in 2015. The prototype was made with use of new technologies such as CNC and 3D-printing, including the dashboard and headlights which were 3D-printed.
Meanwhile, the metricization of America is already taking place. Individual federal agencies, school systems, states and industries, as well as radio announcers, supermarkets, beverage bottlers and ballpark scoreboards, are hastening the everyday use of meters, liters and grams. ...a road sign outside Fergus Falls reads, ST. CLOUD 100 MILES OR 161 KILOMETERS. Other signs note that 55 m.p.h. equals 88 kilometers per hour.
