Common mistakes
- Mixing mph with knots in navigation; 1 kn = 1 nmi/h.
Unit facts
- Miles per hour (mph): Miles per hour is used for road speeds in the US and UK.
- Meters per second (m/s): Meters per second (m/s) is the SI unit of speed; used in physics and engineering.
About Speed
Speed combines distance and time. Science favors m/s, drivers see km/h or mph, and navigation uses knots (nautical miles per hour). Context determines the most convenient representation and rounding.
About Miles per hour (mph)
Miles per hour (mph)
Primary speed unit in the US and parts of the UK. Aviation weather occasionally mixes knots and mph in legacy feeds.
History: Based on the international mile; persisted in road regulations and vehicle instrumentation.
About Meters per second (m/s)
Meters per second (m/s)
SI speed unit, natural in physics equations and simulations. Converts straightforwardly to km/h (×3.6).
History: Rooted in SI coherence; often used in technical specs and safety calculations.
