- Calculation: 5 × 0.277778
- Result: 1.3889 m/s
About the Kilometer/Hour to Meter/Second conversion
The conversion factor from Kilometer/Hour (km/h) to Meter/Second (m/s) is 0.27778, meaning 1 km/h = 0.27778 m/s and inversely 1 m/s = 3.6 km/h. That makes the Meter/Second the larger of the two units in the speed category, where the SI base unit is the meter-per-second. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
