Convert running pace
What the calculator does
The page uses the exact international conversion of one mile to 1.609344 kilometres. It converts pace to speed, then multiplies the pace by distance for track splits and race times. It does not apply a fatigue model.
Pace conversion versus race prediction
A pace conversion answers “what is this same speed in another unit?” A race time predictor calculator answers “how might performance change over another distance?” Use the half-marathon time predictor when that distance is the goal.
