How many kilometres per hour are in a metre per second?

1 metre per second = 3.6 kilometres per hour. In the other direction, 1 kilometre per hour = 0.277777778 metres per second.

What is a metre per second?

Metres per second is the SI unit of speed and the base for every other unit on this page. Physics and meteorology use it directly.

Kilometres per hour is the speed unit on road signs and speedometers in most of the world.

Unit-To-Unit Speed conversion

1 metre per second = 3.6 kilometres per hour

Multiply by 3.6. Metres per second is the physics unit and the meteorological one; km/h is the civil one, and 3.6 is the only bridge you need.

Formula km/h = m/s × 3.6

Metre per second (m/s) max 24 digits

Kilometre per hour (km/h) max 24 digits

Multiply by 3.6, or multiply by 4 and take off 10%. 10 m/s is about 36 km/h.

Weather services and physics use metres per second, while road speeds use km/h. A wind of 20 m/s is 72 km/h.

Divide by 3.6 to go back from km/h, not by 3.6 km. A speed of 36 km/h is only 10 m/s.

The factor 3.6 is simply 3,600 seconds in an hour divided by 1,000 metres in a kilometre.
