Kilometer per hour to Meter per second Formula & Unit Definitions
One kilometer per hour equals exactly 1/3.6 meters per second (≈ 0.277778 m/s). To convert kilometers per hour to meters per second, divide by 3.6 (or multiply by 0.277778). Conversely, to convert meters per second to kilometers per hour, multiply by 3.6.
Quick Estimation: To mentally convert km/h to m/s, divide the speed by 3.6. For example, 72 km/h / 3.6 = exactly 20 m/s.
Kilometer per Hour Scale (km/h)
Global Standard Road Speed- Creator & Origin: Codified under the metric system following the French Revolution.
- Standard Definition: Travel of 1,000 meters in a duration of 3,600 seconds (1 km in 1 h).
- Everyday Focus: Road speed limits in 90% of countries, cycling speed, and train velocity.
Meter per Second Scale (m/s)
SI Base Coherent Velocity Unit- Creator & Origin: The foundational velocity standard of the International System of Units.
- Standard Definition: Distance of 1 meter traveled in 1 second of atomic time.
- Everyday Focus: Physics kinematics, ballistics, wind speed, and fluid flow modeling.
Frequently Asked Questions
Q.How many meters per second is one kilometer per hour?
One kilometer per hour equals exactly 1/3.6 meters per second, or approximately 0.277778 m/s.
Q.What is the formula to convert km/h to m/s?
The formula is: m/s = km/h / 3.6 (or km/h × 0.277778). For example, 90 km/h / 3.6 = 25 m/s.
Q.How do I reverse this calculation from m/s to km/h?
To convert m/s back to km/h, multiply by 3.6. You can also use our Meter per second to Kilometer per hour Converter.
Q.Why is the factor exactly 3.6?
Because 1 km = 1,000 meters and 1 hour = 3,600 seconds. 1,000 / 3,600 = 1 / 3.6.
