Glossary

Meter per second (m/s)

The meter per second is the SI derived unit of speed, defined as the distance of one meter travelled in one second. It is the standard unit in physics and engineering. Useful conversions: 1 m/s = 3.6 km/h = 2.2369 mph = 1.9438 knots. Wind speeds, projectile velocities and free-fall figures are typically reported in m/s in scientific contexts.

Mile per hour (mph)

A mile per hour is the customary speed unit used in the United States, the United Kingdom and a few other countries for road traffic, athletic events and weather reports. 1 mph = 1.6093 km/h = 0.4470 m/s. Typical US highway limits are 55–75 mph; a 100 m sprinter peaks at about 27 mph; a hurricane is sustained winds above 74 mph.

Metric / SI speed

In the metric system, speed is reported in meters per second (scientific) or kilometers per hour (everyday). The relation is exact: 1 m/s = 3.6 km/h. Most countries use km/h on road signs and speedometers; m/s appears in physics, engineering, weather data and athletics where fine-resolution timing matters.

Imperial / US Customary speed

In the United States, the United Kingdom and a few other countries, road speeds are reported in miles per hour (mph). US engineering also uses feet per second (ft/s). 1 mph = 1.6093 km/h = 0.4470 m/s. Maritime and aviation worldwide use knots (1 knot = 1.852 km/h), independent of the metric/imperial divide.
