What is a Mile per hour and a Foot per second?
Miles per hour (mph, MPH, or mi/h) is an imperial and US customary unit of speed expressing the number of statute miles traveled in one hour.
Feet per second (ft/s, fps, or ft/sec) is a unit of speed in the imperial and US customary systems. It measures the distance in feet traveled in one second.
Note: The Mile per hour is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Foot per second belongs to the imperial/US customary system.
History of the Mile per hour and Foot per second
Miles per hour became prominent with the rise of automotive transportation in countries using the imperial system, particularly the United Kingdom and the United States. It provided a practical measure for road travel speeds and regulations.
The foot as a unit of length has ancient origins, and the second became standardized more recently. Feet per second emerged as a logical unit for measuring speed in contexts where feet were the standard measure of distance, particularly before widespread metrication.
Common Uses for miles per hour and feet per second
Explore the typical applications for both Mile per hour (imperial/US) and Foot per second (imperial/US) to understand their common contexts.
Common Uses for miles per hour
- Road Traffic (US/UK): The standard unit for speed limits and vehicle speeds (speedometers) in the United States, United Kingdom, and a few other countries.
- Rail Transport (US/UK): Often used for train speeds in these same countries.
- Meteorology (Informal): Sometimes used informally in the US/UK for wind speed in public weather reports, though knots or m/s are preferred in official meteorological contexts.
- Sports: Used in some sports like baseball (pitch speed) and sometimes informally in running or cycling in relevant countries.
Common Uses for feet per second
- Physics & Engineering (Imperial/US): Used in calculations involving velocity and acceleration in systems using imperial units, particularly in older texts or specific industries (e.g., some aerospace applications).
- Ballistics: Often used to measure the muzzle velocity of firearms.
- Fluid Dynamics (Imperial/US): Can be used to express the speed of fluid flow in pipes or channels in US customary units.
- Some Scientific Instruments: Certain instruments might output readings in ft/s depending on their design and intended application region.
Frequently Asked Questions
Questions About Mile per hour (mph)
Which countries use mph for speed limits?
Miles per hour is primarily used for road speed limits in the United States, the United Kingdom, and some Caribbean nations.
Is mph an SI unit?
No, mph is part of the imperial and US customary systems. The SI unit for speed is meters per second (m/s).
How do you convert mph to km/h?
Multiply the speed in mph by 1.60934. So, 60 mph is approximately 96.6 km/h.
How do you convert mph to ft/s?
Multiply the speed in mph by 1.46667. So, 60 mph is approximately 88 ft/s.
About Foot per second (ft/s)
Is ft/s commonly used for everyday speed?
No, miles per hour (mph) is much more common for everyday speeds (like driving) in countries using the imperial/US customary system. ft/s is more technical.
Is ft/s an SI unit?
No, it belongs to the imperial and US customary systems. The SI unit for speed is meters per second (m/s).
How do you convert ft/s to mph?
Divide the speed in ft/s by 1.46667. So, 88 ft/s is approximately 60 mph.
How do you convert ft/s to m/s?
Multiply the speed in ft/s by 0.3048. So, 10 ft/s is equal to 3.048 m/s.
