Convert running pace to speed and treadmill settings

Turn minutes and seconds into one number

For speed in kilometers per hour, divide 3,600 by pace in seconds per kilometer. A pace of 5:30 is 330 seconds, not 5.30 minutes. The speed is therefore 3,600 ÷ 330, approximately 10.91 km/h.

To convert between miles and kilometers, use 1 mile = 1.609344 km. Multiply minutes per kilometer by that factor to obtain minutes per mile. Convert the time to seconds first so the decimal calculation does not confuse clock notation with ordinary decimal numbers.

Keep a small reference table

For example, 6 mph means six miles in one hour, so each mile takes ten minutes. Its kilometer pace is 600 ÷ 1.609344 = approximately 372.82 seconds, displayed as 6:13. The underlying value has not become exactly 373 seconds merely because the label was rounded.

A setting is not a measured outdoor result

The conversion tells you what the selected units mean. It does not verify the treadmill's belt speed or establish an exact outdoor equivalent. Keep the displayed setting, any separate sensor reading and your recorded activity summary distinct if they disagree.

Incline introduces another setting that the unit conversion does not account for. There is no incline input in this simple arithmetic. Do not describe a particular setting as reproducing a specific outdoor course merely because its displayed speed matches your target pace.

Check the intended distance and time

Use the Runome pace calculator to convert a distance and duration or solve for a target time. It displays metric and imperial pace and speed. Keep your chosen unit visible when copying the result into a training note or share card.

For a race-specific application, follow the 5K example or the 10K example. Those guides add cumulative checkpoints so the converted pace has a clear relationship to a finish-time target.
