Frequently asked questions

How do you turn pace into speed?

Speed in km/h is 3600 divided by the seconds per km. A 5:00 per km pace is 300 seconds, so 3600 divided by 300 gives 12 km/h.

What mile pace matches 5:00 per km?

Multiply the per-km seconds by 1.609344. So 300 seconds becomes about 482.8 seconds, which is roughly 8:03 per mile.

How many kilometres are in a mile?

One mile is exactly 1.609344 kilometres, the value used here for every pace and speed conversion.

Can I enter speed instead of pace?

Yes. Pick km/h or mph as the input and the tool returns the equivalent pace per km and per mile alongside both speeds.

What pace format is used?

Paces are shown as minutes and seconds, like 8:03, and you can also type that format in. Seconds are rounded to the nearest whole second.
