To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into meters per second To convert from m/s into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.Ģ.2352 (m/s) / 0.44704 = 5 mph To simply convert from any unit into meters per second, for example, from 5 mph, just multiply by the conversion value in the right column in the table below.ĥ mph * 0.44704 = 2.2352 m/s Where S is our starting value, C is our conversion factor, and

How to Convert Units of SpeedĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: The English system usually expresses speed as miles per hour (mph) or sometimes feet per second (ft/s), while marine vessels typically use knots, or nautical miles per hour. Negative 2 m/s, although your speed is still positive.įor most science applications, the SI unit for speed and velocity is meters per second (m/s), although kliometers per hour (km/h) is sometimes used when measuring the speed of vehicles. Say you were walking backward again your velocity is Velocity is speed in the context of direction. Walk forward or backward at 2 meters per second, and your speed is just that: 2 m/s.
Speed is the rate of change in position of an object, regardless of direction of travel.
