Treadmill Pace Converter

Divide 3600 seconds by the miles-per-hour figure to get seconds per mile, then read it as minutes and seconds. At 6 mph that is 3600 / 6 = 600 seconds, or 10:00 per mile. The tool does this and formats the result for you.

The speed is converted to km/h by multiplying mph by 1.609344, then 3600 is divided by that km/h figure to get seconds per kilometre. Your per-km pace is always faster in clock terms than your per-mile pace because a kilometre is shorter than a mile.

No. Incline raises the effort and the calories you burn, but the belt still moves the same distance per minute, so the speed-to-pace conversion is unchanged. The tool records the incline you enter for reference only and does not adjust the pace.

The moving belt reduces some of the work of propelling yourself, and indoors there is no wind resistance. Many runners set a 1 to 2 percent incline to make treadmill effort feel closer to running the same pace outside.

Yes. Switch to 'From pace (per mile)' and enter your target minutes and seconds. The converter turns that into the treadmill speed to set, shown in both mph and km/h.

An 8:00 per mile pace is 7.5 mph, because 8 minutes is 480 seconds and 3600 / 480 = 7.5. That works out to 12.07 km/h and a per-km pace of about 4:58.

The speed slider covers 0.5 to 15 mph in 0.1 steps, which spans a slow walk to a fast run. In pace mode you can enter 0 to 30 minutes and 0 to 59 seconds per mile.

Speeds in mph and km/h are rounded to two decimals, and paces are rounded to the nearest whole second before being shown as minutes and seconds. Small rounding differences of a second are normal.

Yes. The conversion runs entirely in your browser and nothing you enter is sent anywhere.
