About both units

From

Mile per Hour

mph

Miles per hour (mph) is the standard road-speed unit in the US, UK and a few other countries. US highways typically 65–75 mph; UK motorways 70 mph. US weather reports wind speed in mph, while meteorologists also use knots.

Real-world: US interstate: 70 mph typical. UK motorway: 70 mph limit. Cycling pro speed: 25 mph. Tornado winds: 110+ mph.

Centimeter per Second

cm/s

Centimetres per second (cm/s) is used for slow-moving phenomena — ocean currents, earthworms, biological cell motion. Typical ocean surface currents: 10–100 cm/s. Continental drift: about 2–10 cm/year (converted: very slow cm/s).

Real-world: Gulf Stream: 100–200 cm/s. Amoeba: 1 mm/s = 0.1 cm/s. Sediment settling: 0.01–1 cm/s.

Tips & common mistakes

Quick tips

  • 1 mph = 1.609 km/h = 0.447 m/s.
  • Quick convert: mph × 1.6 = km/h.
  • UK speeds posted in mph on road signs despite general metrication.

Avoid these

  • Reading a UK road sign "50" as km/h — it's mph (= 80 km/h).
  • Converting mph to km/h by multiplying by 1.5 instead of 1.609 — 7% error.
  • Assuming "mph" and "MPH" differ — capitalisation does not matter.
