How to convert meters per second to kilometers per hour
One meter per second equals 3.6 kilometers per hour. To convert, multiply the number of meters per second by 3.6:
Mental-math shortcut: Multiply m/s by 3.6: 10 m/s = 36 km/h.
Example
Convert 10 meters per second to kilometers per hour: 10 m/s × 3.6 = 36 km/h.
