How to convert Kilometers per Hour to Meters per Second

Speed units depend on context: road signs use km/h or mph, physics uses meters per second, and ships and aircraft use knots. Converting between them is essential for travel, sport, and science.

Everything converts through meters per second. One km/h is exactly 1/3.6 m/s, one mph is exactly 0.44704 m/s, and one knot is one nautical mile per hour — about 0.5144 m/s.

Formula

km/h × 0.2777777778 = m/s

Multiply your kilometers per hour value by 0.2777777778 to get meters per second. For the reverse, divide by the same factor.
