formula for calculating speed rpm in metric

Speed Calculator - Omni

Average speed formula. Average speed is measured in units of distance per time. Common units are kilometers per hour (kph), miles per our (mph), meters per second (m/s) and feet per second (ft/s). In our calculator the default unit is kph but you can change it to any of the common units.
