Convert running pace between min/km, min/mi, km/h and mph. Free tool for runners and athletes.
Running pace measures the time needed to cover a standard distance, usually expressed in minutes per kilometer (min/km) or minutes per mile (min/mi). Unlike speed, which measures distance per unit of time (km/h), pace is an inverse quantity: a lower pace means a faster run. For this reason, converting between pace and speed is not a simple multiplication — it is an inversion. This difference in direction causes frequent confusion among runners. A pace of 5 min/km corresponds to 12 km/h (60 ÷ 5), not 5 km/h. Meanwhile, 5 min/mi corresponds to about 19.31 km/h, because a mile is longer than a kilometer (1 mile = 1.609344 km). On top of that, Brazilian runners who follow American or British training plans often need to convert between min/km and min/mi, and between km/h and mph. This converter correctly calculates between min/km, min/mi, km/h, and mph, handling the inverse relationships between pace and speed and the difference between kilometer and mile. It is essential for runners following international training plans, athletes comparing performance in mile-measured races (such as US and UK marathons), and anyone using running apps configured in different units.
Divide 60 by the value in min/km. Example: 5 min/km = 60 ÷ 5 = 12 km/h.
Multiply by 0.621371 (1 km = 0.621371 miles). Example: 8 min/mi ≈ 4.97 min/km.
6 min/km = 10 km/h ≈ 6.21 mph.
Pace measures time per distance (min/km); speed measures distance per time (km/h). So a lower pace = a higher speed.
