Pace Calculator

Free running pace calculator. Calculate your pace per km or mile from distance and time.

How the Pace Calculator works

Pace is the time taken per unit of distance, computed by dividing total time by the distance. Speed is the inverse—distance divided by time—typically expressed in km/h or mph. The calculator converts your time into minutes and seconds for an easy-to-read pace format.

Formula

Pace = Time / Distance; Speed = Distance / Time
