Kilometers per hour to meters per second

Kilometers per hour is how cars, trains and weather forecasts describe speed; meters per second is the unit of physics, engineering and sports science. Because an hour has 3 600 seconds and a kilometer has 1 000 meters, the conversion factor is exactly 3.6: m/s = km/h ÷ 3.6.

Mental shortcut

Divide by 4 and add a bit more than 10 %: 100 km/h → 25 + 2.8 ≈ 27.8 m/s. Or remember a few anchors: 36 km/h is exactly 10 m/s, 72 km/h is 20 m/s, 108 km/h is 30 m/s.

  • 10 km/h = 2.78 m/s (a brisk walk)
  • 20 km/h = 5.56 m/s (an easy cycle)
  • 36 km/h = 10 m/s (a fast sprint)
  • 50 km/h = 13.89 m/s (city speed limit)
  • 100 km/h = 27.78 m/s
  • 120 km/h = 33.33 m/s (motorway)
  • 200 km/h = 55.56 m/s
  • 300 km/h = 83.33 m/s (a high-speed train)

Why physics uses m/s

Kinetic energy, momentum, braking distance and drag are all calculated with SI units, and mixing in km/h gives wrong answers by a factor of 3.6 or 12.96. A car at 100 km/h covers 27.8 meters every second — a useful way to explain stopping distances: at a 1-second reaction time the car has already travelled almost 28 m before the brakes touch.

Wind and weather

Meteorologists work in m/s; broadcasts convert to km/h or mph. A 90 km/h gust is 25 m/s, storm force on the Beaufort scale. Hurricane-force wind starts at about 118 km/h, 33 m/s.

Sport

Usain Bolt's 100 m world record averaged 10.44 m/s, 37.6 km/h; his peak speed was about 12.4 m/s, 44.7 km/h. A serve in tennis at 200 km/h crosses the court (23.8 m) in less than half a second.
