How the metres per second to feet per second converter works
Speeds convert through metres per second. 1 km/h is 1000/3600 m/s; 1 mph is 1609.344/3600 m/s; a knot is one nautical mile (1,852 m) per hour. Mach is shown against the standard sea-level speed of sound of 340.29 m/s and varies with altitude and temperature.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about speed conversion
How many ft/s is 1 m/s?
3.2808 ft/s.
What is 343 m/s?
1,125 ft/s — the speed of sound at 20 °C.
What is 26.8 m/s?
88 ft/s, or 60 mph.
Why convert?
Because physics works in m/s and US engineering standards frequently do not.
What is a bullet velocity?
Rifle rounds run 700 to 1,200 m/s, which is 2,300 to 3,900 ft/s.
