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.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

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.
