How to convert kilometers per hour (km/h) to meters per second (m/s)
We convert by pivoting through the SI base unit for Speed and applying exact factors where applicable.

Examples
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Mixing mph with knots in navigation; 1 kn = 1 nmi/h.
About Speed
Speed combines distance and time. Science favors m/s, drivers see km/h or mph, and navigation uses knots (nautical miles per hour). Context determines the most convenient representation and rounding.
About Kilometers per hour (km/h)
Kilometers per hour (km/h)
Road and vehicle speed standard in most of the world. Convert from m/s by multiplying by 3.6.
History: Adopted with metric traffic systems and signage during 20th-century metrication.
About Meters per second (m/s)
Meters per second (m/s)
SI speed unit, natural in physics equations and simulations. Converts straightforwardly to km/h (×3.6).
History: Rooted in SI coherence; often used in technical specs and safety calculations.
