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?

Speed of sound varies

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.
