UnitConMeters per Second to KM/H Converter
Convert meters per second to kilometers per hour for athletics, wind speed, and physics problems where scientific SI speed values need to be expressed in more relatable road-speed terms.
Formula
Multiply meters per second by 3.6 to get km/h. To reverse, divide km/h by 3.6 to get m/s.

About these units
Meter per Second
The meter per second is the SI coherent unit of speed, derived from the base units of meter and second. It is used universally in physics and engineering calculations.
Kilometer per Hour
The kilometer per hour is a convenient derived unit for everyday speed, equal to 1000 m / 3600 s = 1/3.6 m/s. It is the standard for road speed limits and vehicle speedometers in most countries.
Frequently asked questions
10 × 3.6 = 36 km/h.
Usain Bolt's 9.58-second record over 100 m equals approximately 10.44 m/s or 37.58 km/h at average speed — his peak speed exceeded 12 m/s (43.2 km/h).
25 × 3.6 = 90 km/h.
