Pace To Speed Calculator

Work out pace to speed instantly with clear inputs, formula shown and shareable results.

About Pace To Speed Calculator

Pace and speed are reciprocals: speed in km/h is 60 divided by pace in minutes per kilometre. A 5:30 per kilometre pace is 10.91 km/h, or 3.03 m/s, and works out at 8:51 per mile. Because the relationship is inverse, a fixed pace improvement is worth more speed at slow paces than at fast ones.

Formulas

Speed from pace

km/h = 60 / pace in min/km

Mile pace

min/mile = min/km x 1.609344

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

Why does 30 seconds per kilometre matter more when slow?

Because the relationship is reciprocal. Going from 7:00 to 6:30 gains 0.66 km/h; from 4:00 to 3:30 gains 2.1 km/h.

What pace is a four-hour marathon?

About 5:41 per kilometre, or 9:09 per mile - just over 10.5 km/h.
