Step-by-Step
How to Convert Meters per Second to Kilometers per Hour
Converting m/s to km/h is simple when you multiply the speed by 3.6.
The Formula
Meters per second and kilometers per hour are both standard units of speed used in science, transport, athletics, engineering, and technical measurements. The exact relationship is 1 m/s = 18/5 km/h.
To convert kilometers per hour back to meters per second, divide by 3.6.
How to Turn m/s into km/h — Step by Step
Write down the speed value
Identify the number of meters per second you want to convert — for example, 20 m/s.
Multiply by 3.6
20 m/s × 3.6 = 72 km/h. This gives you the equivalent speed in kilometers per hour.
Label your answer
Always write the unit (km/h) after the number so the result is clear and unambiguous.
m/s vs km/h
What Is the Difference Between Meters per Second and Kilometers per Hour?
Meters per second and kilometers per hour are both units of speed. Meters per second are widely used in science, engineering, and physics, while kilometers per hour are commonly used for road speeds, transport, and everyday driving measurements.
The relationship used on this page is: 1 m/s = 3.6 km/h. To convert meters per second to kilometers per hour, multiply the number of m/s by 3.6.
For example, 10 m/s = 36 km/h, 20 m/s = 72 km/h, and 27.777778 m/s = 100 km/h.
This conversion is exact and is commonly used in vehicle speed calculations, athletics, motion analysis, engineering, and technical documents.
