How many Feet per second equal one Mile per hour?
By definition, 5280 feet euqal one mile and 3600 seconds equal one hour. Taking the two dimensions into account we can calculate that approximately 0.681818 feet per second equal one mile per hour (3600/5280). Historically, the mile varied in length, until it was fixed with an international treaty in 1959. The internationally recognized symbol for miles is "mi" and for feet is "ft". Still, in some places in the US and the UK "m" is used to denote miles, which can lead to confusion with the SI unit "m", which stands for meter. This transfers into the derived units of speed: fps instead of ftps, and mph instead of miph.
Difference between Feet per second and Miles per hour
Both feet and miles are units for measuring distances and dimensions, but with very different magnitude. Due to this, miles per hour are usually used to measure the speed of cars, trucks, or trains, while feet per second are used for smaller distances like in running or walking, or when greater precision is required, such as in physics and engineering.
Both units have a long history and varied in definition from time to time and from place to place. The foot, however, is much older than the mile, despite the mile being used as early as the Roman Empire.
How to convert Feet per second to Miles per hour
To convert from feet per second to miles per hour you need to take into account the conversions on both the length dimension and the time dimension. In terms of length, divide the measurement in feet by 5280 to get the equivalent in miles. In terms of time, we need to multiply 1 second by 3600 to get 1 hour. Combined, the conversion results in a multiplication by 3600/5280, or about 0.681818 or, alternatively, a division by 1.466667. The conversion is often done with the help of a calculator. Our online feet per second to miles per hour converter will surely make that easy for you, and it also has a one-click copy button.
Feet per second to Miles per hour conversion example
Sample task: convert 10 feet per second to miles per hour. Solution (first method):
Formula:
fps * 0.681818 = mph
Calculation:
10 fps * 0.6818 = 6.818180 mph
End result:
10 fps is equal to 6.818180 mph
Solution (second method):
Formula:
fps / 1.466667 = mph
Calculation:
10 fps / 1.4667 = 6.818180 mph
End result:
10 fps is equal to 6.818180 mph
