Convert instantly between kilometre pace, mile pace and speed units, with the corresponding finish times for 5K, 10K, half marathon and marathon.
Frequently Asked Questions
How do I convert min/km to min/mile?
One mile is 1.609344 km, so min/mile = min/km × 1.609344. For example 5:00/km ≈ 8:03/mi.
Why do treadmills show mph?
Treadmills in the US/UK usually display speed in mph (1 mph ≈ 1.609 km/h) rather than pace.
Are the conversions exact?
The unit conversions are mathematically exact. Finish-time projections are linear estimates and ignore fatigue.
