Use this tool to quickly convert speed between meters/s, kilometers/h, miles/h, feet/s, knots and speed of sound.

Meters per second (m/s) is a unit of speed or velocity in the International System of Units (SI). It represents the distance traveled in meters per one second of time.

Kilometers per hour (km/h) is a unit of speed commonly used in many countries. It measures the distance traveled in kilometers within one hour, providing a metric measurement of velocity.

Miles per hour (mph) is a unit of speed predominantly used in the United States and some other countries. It measures the distance traveled in miles within one hour.

Feet per second (ft/s) is an imperial unit of speed or velocity. It measures the distance traveled in feet within one second, commonly used in certain engineering and physics contexts.

Knots (kt) are a unit of speed used primarily in aviation and maritime contexts. One knot is equal to one nautical mile per hour, providing a measure of speed over water or through the air.

The speed of sound varies depending on factors like temperature and medium. In dry air at 20°C (68°F), it's abut 340 meters per second.
