About converting Km per Hour to Meter per Sec

Converting Km per Hour to Meter per Sec is a common speed conversion. One km per hour (km/h) equals 0.277777778 meter per sec (m/s). Kilometers per hour are used for road speed limits in most countries outside the US.

This conversion is commonly needed for sailing and marine navigation, physics and engineering calculations, driving and speed limit compliance. Meters per second is the SI unit for speed, used in physics and engineering.

To put km per hour in perspective: a high-speed train (300+ km/h). In meter per sec, common references include a brisk walk (about 1.4 m/s).

Did you know?

Most of the world sets speed limits in kilometers per hour, with the notable exceptions of the United States, the United Kingdom, and a handful of other countries.

Real-world examples
Km per Hour (km/h)
  • a jogger (about 10 km/h)
  • a highway speed limit (100–120 km/h)
  • a high-speed train (300+ km/h)
Meter per Sec (m/s)
  • a brisk walk (about 1.4 m/s)
  • world-record 100m sprint (about 10.4 m/s)
  • speed of sound at sea level (343 m/s)
Did you know?

Meters per second is the SI derived unit for speed, calculated simply as distance in meters divided by time in seconds — the standard unit in physics equations worldwide.
