Where you'll actually use this
Speed measures distance covered per unit of time. Common units include km/h, mph, m/s, knots, and the speed of light (c).
- Driving
Speed limits use km/h in most countries; mph in the US, UK, and a few others.
- Aviation & maritime
Planes and ships report speed in knots (nautical miles per hour) — 1 kn ≈ 1.852 km/h.
- Running & cycling
Pace apps switch between min/km and min/mi; speed in km/h vs mph depending on locale.
Common mistakes to avoid
- kph isn't a real unit
The correct abbreviation is km/h. 'kph' is informal and not used in technical writing.
- Knots already includes 'per hour'
Saying 'knots per hour' is redundant — it's just 'knots'.
Did you know?
Mach 1 isn't a fixed speed — it depends on temperature. At sea level it's roughly 1,225 km/h, falling to ~1,062 km/h at altitude.
