Miles per Hour to Feet per Second Conversion
Converting Miles per Hour (mph) to Feet per Second (ft/s) is a common speed conversion. 1 mph equals 1.466667 ft/s. For example, 100 mph is equal to 146.666667 ft/s.
Quick Mental Math: Miles per Hour to Feet per Second
Multiply by 1.5: 100 miles per hour = 147 feet per second.
Why is converting Miles per Hour to Feet per Second tricky?
Decimal multipliers introduce rounding errors in mental math.
Quick Reference Values
1 mph = 1.466667 ft/s. 5 mph = 7.333333 ft/s. 10 mph = 14.666667 ft/s. 25 mph = 36.666667 ft/s. 50 mph = 73.333333 ft/s. 100 mph = 146.666667 ft/s.
What is Miles per Hour?
Miles per Hour (mph) is a unit of speed. Miles per hour measure speed as miles traveled in one hour. One mile equals 1,609.344 meters, so 1 mph equals approximately 0.44704 meters per second [bipm-si-brochure]. This unit is widely used for vehicle speed and speed limits in non-metric countries. Miles per hour originated from the mile and hour units standardized in the British Imperial system. It became common in transportation with the rise of automobiles and was internationally recognized with the mile's 1959 definition [bipm-si-brochure]. The USA, United Kingdom, and several Commonwealth nations use mph for road speed limits and vehicle speeds. It remains standard in aviation and motorsports within these countries, despite metrication efforts [nist-sp-811].
What is Feet per Second?
Feet per Second (ft/s) is a unit of speed. Feet-per-second measures speed as feet traveled in one second. It converts to meters per second by multiplying feet by 0.3048. This unit is common in physics, ballistics, and engineering to express rapid velocities [iso-80000]. Feet-per-second became standardized with the development of modern physics and engineering in the late 19th and early 20th centuries. It was adopted for precise, short-interval velocity measurements in the imperial system [nist-si-guide]. Feet-per-second is widely used in the United States for projectile speeds, fluid flow velocities, and mechanical motion. It is less frequent outside imperial system countries, where meters per second is preferred [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: miles per hour, mile per hour, mi/h, mphs, feet per second, ft per second, feet/sec, fps. All of these refer to the Miles per Hour to Feet per Second conversion.
