Kilometers Per Hour to Meters Per Second Formula & Math
To convert from kilometers per hour to meters per second, you divide by 3.6:
Primary Formula:m/s = km/h / 3.6
Reverse Formula:km/h = m/s × 3.6
Step-by-Step Calculation Example
Suppose you need to convert 72 kilometers per hour into meters per second:
- Apply the base formula:
m/s = km/h / 3.6 - Substitute the value:
72 ÷ 3.6 = 20 m/s - Result: 72 kilometers per hour equals exactly 20 m/s.

Frequently Asked Questions
How many meters per second is 100 km/h?
100 km/h equals approximately 27.78 m/s (100 ÷ 3.6 ≈ 27.778 m/s).
How many meters per second is 50 km/h?
50 km/h equals approximately 13.89 m/s (50 ÷ 3.6 ≈ 13.889 m/s).
Why is m/s preferred over km/h in physics?
Meters and seconds are fundamental base units in the SI system ($kg, m, s$). Calculations of kinetic energy ($E_k = frac{1}{2}mv^2$) and momentum ($p = mv$) require velocity in m/s to yield joules and newton-seconds directly without conversion factors.
