Exact conversion

Kilometers Per Hour to meters per second formula

m/s = km/h × 0.277777778

1 km/h equals 0.277777778 m/s. 10 km/h equals 2.77777778 m/s.

About these units

km/h
Kilometers per hour, a metric speed unit used for road speeds, weather, transport, and general speed reporting. It equals the number of kilometers traveled in one hour.
m/s
Meters per second, the SI-derived speed unit for meters traveled each second. It is common in physics, engineering, sports timing, and scientific calculations, and it is different from acceleration units such as m/s^2.

km/h to m/s context and checks

Best use
Use speed conversions for travel, training, weather, aviation, marine, and physics values where distance is measured per unit of time.
Common mistake
Do not use speed pages for simple distance conversion. Nautical miles per hour, kilometers, and knots describe different ideas.
Precision note
Keep units attached to the value so a speed result is not mistaken for distance, pace, or acceleration.

Example check: 1 km/h converts to 0.277777778 m/s. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
