Convert speed units, meters per second, miles per hour, kilometers per hour
Speed is defined as the rate of change in position, expressed as distance traveled per unit of time. Speed is a scalar quantity with dimensions distance/time. Velocity is a vector quantity, the rate at which an object changes it's position.
In order to calculate speed, the formula is :
Speed = Distance / Time
Speed unit in SI system is meters per second (mps).
Other speed units such as miles per hour (mph), kilometers per hour (kph) are also widely used.
