Pace means time per unit of distance. The calculator matches your units automatically.
Miles, kilometers, and track sessions
Enter distance in kilometers, miles, meters, or yards. Use minutes per kilometer, per mile, or per 400 meters for pace. Changing a unit converts your value.
A mile is exactly 1,609.344 meters. Half marathon and marathon presets use 21.0975 km and 42.195 km. Results round to the nearest second and distances to three decimal places; calculations retain full precision.
Made to be useful. Kept simple.
