Convert kmh to mps

One kilometer per hour equals 0.277778 meters per second. To convert any number of kilometers per hour to meters per second, multiply by 0.27777778.

The converter above works in both directions and updates as you type. Below you will find the formula, a worked example and a reference table of common values.

Speed conversions divide by audience. Road speeds move between kilometres and miles per hour and are what a driver or a runner needs. Metres per second is what every equation of motion expects, so it is the form any physics problem has to reach. Knots belong to the sea and the air, where one knot is one nautical mile per hour and a nautical mile is one minute of latitude — a system built around navigation rather than around convenience.

kmh to mps formula

To go the other way, use kilometer per hour = meter per second ÷ 0.27777778.

About these units

Kilometres per hour is the road-speed unit in most of the world. Dividing by 3.6 converts it to metres per second, the SI unit physics uses.

Metres per second is the SI speed unit and the one every equation of motion expects. Wind speeds in meteorology are usually reported in it.

Kilometer per hour is also written kilometres per hour, kmh, kph, kmph, km/hr and kmh. Meter per second is also written metres per second, meters per second, mps and ms-1.
