Speed Converter
Convert between 5 speed units.
About Speed
Speed is distance divided by time, so every conversion is really two at once. The ones worth remembering: 1 m/s is 3.6 km/h, and 1 mph is 1.609 km/h. Knots are nautical miles per hour, used at sea and in aviation, where 1 knot is 1.852 km/h. A 100 km/h motorway limit is about 62 mph.
