Convert m/s → km/h
About this conversion
One m/s equals 3.6 km/h. Converts scientific speed into everyday metric speed — multiply by 3.6.

Why this conversion matters
Wind speed, ball speed and sprint velocity are frequently captured in m/s by scientific instruments (anemometers, radar guns, tracking cameras) but reported to spectators and athletes in the more intuitive km/h — this converter bridges raw sensor data and race-day/match-day numbers.
FAQ
Why convert m/s to km/h for wind readings?
Wind-assistance rules in athletics (sprints and jumps) are defined in m/s, but weather forecasts and general wind-speed reporting almost always use km/h or mph, so converting between them is routine for athletics officials and fans.
What km/h is the legal wind-assistance limit in sprinting?
The IAAF/World Athletics limit is +2.0 m/s, which is 7.2 km/h — any tailwind reading above this voids a sprint or jump record.
How fast in km/h is an elite 100m sprinter's peak velocity?
Elite male sprinters reach roughly 12-12.5 m/s at peak velocity, which converts to around 43-45 km/h.
