Convert Kilometers per hour (km/h) to Meters per second (m/s)

Category: Speed

0.277778 ms

1 kmh = 0.277778 ms

Precision: 6 decimals; very small non-zero results use significant digits.

How to convert kilometers per hour (km/h) to meters per second (m/s)

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.

Conversion formula

Use the following formula:

Meters per second (m/s) ≈ Kilometers per hour (km/h) × 0.277777777778

Convert speed from Kilometers per hour (km/h) to Meters per second (m/s) using a fixed unit ratio. Round only the final result.

Common mistakes

  • Mixing mph with knots in navigation; 1 kn = 1 nmi/h.

Unit facts

  • Kilometers per hour (km/h): Kilometers per hour is the common road-speed unit in most of the world.
  • Meters per second (m/s): Meters per second (m/s) is the SI unit of speed; used in physics and engineering.

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.
