Acerca de Speed Converter
Car speedometers read km/h or mph depending on the country, physics uses m/s, aviation uses knots, and ballistics uses ft/s. This converter covers all five from one input: type a value, pick its unit, and every other unit appears instantly — 100 km/h is 62.14 mph, 27.78 m/s and about 54 knots. Handy for driving abroad, reading research papers and decoding weather reports.
