About Speed Converter — Free Online Converter
Speed Converter turns a velocity into any of eight units: metres and centimetres per second, kilometres per hour, miles per hour, feet per second, knots, Mach and the speed of light.
Metres per second is the base, with the knot taken as 1852/3600 and the mile per hour as exactly 0.44704, so a km/h-to-mph answer matches a road-sign conversion table. Mach is the entry that needs a caveat and it carries one into the result: Mach is a ratio to the local speed of sound, which moves with air temperature, and this tool uses one fixed value of 340.29 m/s — the standard-atmosphere figure at sea level and 15 degrees Celsius. In colder or thinner air the true Mach number differs, so treat it as a reference conversion and not as a reading for a particular flight.
No part of this runs on a server. The value is multiplied by a constant that is already sitting in the page, which is why the network tab stays empty and there is nothing to delete afterwards.
Making sense of a speed limit abroad, converting a cycling or running pace, reading a marine or aviation wind speed given in knots, and turning a laboratory figure in m/s into km/h.
