1 m/s = 3.6 km/h
1 meter per second equals 3.6 kilometers per hour. To convert meters per second to kilometers per hour, multiply the meter per second value by 3.6. For quick reference: 1 m/s = 3.6 km/h, 5 m/s = 18 km/h, 10 m/s = 36 km/h, 100 m/s = 360 km/h.
Kilometers per hour = Meters per second × 3.6Start with your value in meters per second.
Multiply the meter per second value by 3.6. This is the exact conversion factor from meters per second to kilometers per hour.
The product is your value in kilometers per hour. For example, 5 m/s × 3.6 = 18 km/h.
The exact factor from meters per second to kilometers per hour is 3.6.

A brisk walking pace is about 1.4 m/s. An Olympic 100 m sprinter peaks above 12 m/s. In kilometers per hour, that gives you: 1 m/s = 3.6 km/h, 10 m/s = 36 km/h, 100 m/s = 360 km/h.
The meter per second (m/s) is the SI derived unit of speed. It is the preferred unit in physics, engineering, and any scientific context. The speed of light in vacuum is exactly 299,792,458 m/s, which is how the meter itself is now defined.
The kilometer per hour (km/h) is the standard speed unit on road signs almost everywhere except the United States and the United Kingdom. To convert to meters per second, divide by 3.6 (since 1 km = 1000 m and 1 h = 3600 s).
