Feet per Second to Meters per Second Converter
Convert feet per second to meters per second — one foot per second is exactly 0.3048 m/s. Results update as you type; exact factors shown.
One foot per second is 0.3048 meter per second — see the exact factor, not a rounded rule of thumb.
How the feet per second to meters per second converter works
Speeds convert through meters 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 US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.
