About the units

What is a kilometer per hour?

Kilometers per hour (km/h) is the standard road-speed unit in most countries. 100 km/h equals 62.14 mph or 27.78 m/s.

What is a meter per second?

Meters per second (m/s) is the SI unit of speed. Physics calculations and wind speeds in scientific contexts use m/s; 1 m/s equals exactly 3.6 km/h.

Frequently asked questions

How many meters per second are in 1 kilometer per hour?

1 kilometer per hour (km/h) = 0.2777777778 meters per second (m/s).

What is the formula to convert kilometers per hour to meters per second?

meters per second = kilometers per hour × 0.2777777778 — multiply the kilometer per hour value by 0.277778.

How do I convert km/h to m/s without a calculator?
