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.

Metric system

 metre per second m/s metre per minute m/min metre per hour m/h kilometre per second km/s kilometre per minute km/min kilometre per hour km/h

United States customary units / Imperial units

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

Speed conversion formula

Metric system

$1m/s = 60m/min = 60 \times 60m/h$
$1m/h = {\dfrac {1}{60}}m/min = {\dfrac {1}{60 \times 60}}m/s$
$1m/s = {\dfrac {1}{1000}}km/s = {\dfrac {60}{1000}}km/min = {\dfrac {60 \times 60}{1000}}km/h$
$1km/h = 1000m/h = {\dfrac {1000}{60}}m/min = {\dfrac {1000}{60 \times 60}}m/s$

United States customary units / Imperial units

$1fps = 60fpm = 60 \times 60fph$
$1mps = 60mpm = 60 \times 60mph$

$1mps = 5280fps \\ (1mi = 5280ft)$

$1fps = 0.3048 m/s \\ (1ft = 0.3048m)$

その他

Knot

$1kn = 1nm/h = 1852m/h$

Mach number

$1M = 340m/s$

Speed of light

$c = 299792458 m/s$
