Speed Converter / Tool

Converts the entered unit of speed to another unit.
(km/s, km/min, km/h, fps, fpm, fph, Knot, etc.)

  • Rounded to the fourteenth decimal place.

A number with many digits may appear as "1e9". This is the computer's exponential representation, where "e" is a power of 10.
1e3 = 103 = 1,000
1e6 = 106 = 1,000,000
1e9 = 109 = 1,000,000,000
1e-3 = 10-3 = 0.001
1e-6 = 10-6 = 0.000001
1e-9 = 10-9 = 0.000000001
