Convert Kilometers per hour to meters per second
1 kilometer per hour = 0.277778 meters per second · m/s = km/h ÷ 3.6
When you need this conversion
This conversion goes from kilometers per hour, the road speed unit in most countries, to meters per second, the SI speed unit used in physics. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
m/s = km/h ÷ 3.6Because both units measure speed, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.
