Miles per hour to Kilometers per hour table Miles per hour Kilometers per hour 45 mph 72.42 km/h 46 mph 74.03 km/h 47 mph 75.64 km/h 48 mph 77.25 km/h So at 60 mph it is traveling 88 feet per second. To convert miles per hour to feet per second, multiply the number of miles per hour by 1.47. If you are moving at a speed of 40 mph, how many feet do you travel in one second? At 40 miles per hour, you are traveling at 58.8 feet per second.
The international foot corresponds to human feet with shoe size 13 (UK), 14 (US male), 15.5 (US female), or 46 (EU).Convert 45 Miles per Hour to Feet per Second mph fps 45.00 66 45.01 66.015 45.02 66.029 45.03 66.044 How many mph are in an FT?ġ foot per hour (ft/h) = 0.00019 miles per hour (mph) Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain). In the US, feet and inches are commonly used to measure height, shorter distances, field length (sometimes in the form of yards), etc. While the United States is one of the few, if not only, countries in which the foot is still widely used, many countries used their own version of the foot prior to metrication, as evidenced by a fairly large list of obsolete feet measurements.Ĭurrent use: The foot is primarily used in the United States, Canada, and the United Kingdom for many everyday applications. This resulted in the measurement of a foot varying between 250 mm and 335 mm in the past compared to the current definition of 304.8 mm. The various lengths were due to parts of the human body historically being used as a basis for units of length (such as the cubit, hand, span, digit, and many others, sometimes referred to as anthropic units).
History/origin: Prior to standardization of units of measurement, and the definition of the foot currently in use, the measurement of the foot was used in many different systems including the Greek, Roman, English, Chinese, and French systems, varying in length between each. One foot contains 12 inches, and one yard is comprised of three feet. A foot was defined as exactly 0.3048 meters in 1959. Footĭefinition: A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement. There also exist a number of units based on, or closely related to, the Roman mile, including the nautical mile (1.852 km exactly), Italian mile (~1.852 km), and the Chinese mile (500m exactly).Ĭurrent use: Although most countries have adopted the metric system and use kilometers, rather than miles, to express land distance, the mile is still prevalently used in countries such as the United States (US), United Kingdom (UK), Myanmar, and Liberia, as well as some other countries which are either US or UK territories, or have historical ties with either country. The definition of a mile as 5,280 feet (or 8 furlongs), sometimes referred to as the statute mile, international mile, or land mile, which differs from the Roman mile of 5,000 feet, developed due to the importance of the furlong in England, back in 1593. The use of the abbreviation "m" for mile was common before the widespread adoption of the metric system after the adoption of the metric system, "mi" became the preferred abbreviation in order to avoid confusion between miles and meters. History/origin: The mile is an English unit (predecessor of Imperial units and United States Customary Units) of length. It is currently defined as 5,280 feet, 1,760 yards, or exactly 1,609.344 meters. Definition: A mile (symbol: mi or m) is a unit of length in the imperial and US customary systems of measurement.
