Show the math
Pace and speed are reciprocals of each other:
speed = 3,600 ÷ pace-in-seconds
A pace of 5:00 per kilometre is 300 seconds, so the speed is 3,600 ÷ 300 = 12 km/h. Edit either the pace or the speed and the other updates instantly, handy for matching a training plan to a treadmill display.
What this does
A pace-to-speed converter switches between running pace (min/km or min/mile) and speed (km/h or mph) instantly, handy for treadmills and pace charts.
How it works
Pace and speed are reciprocals. A pace in seconds per km converts to km/h, and the tool handles miles too, so both fields update together.
Speed = 3,600 ÷ pace in seconds
How to use it
- Enter a pace or a speed.
- Choose km or miles.
- Read the converted value.
- Use it to set a treadmill speed.
Understanding your result
Treadmills usually show speed while training plans give pace, so this conversion lets you dial in the right setting.
Example
A 5:00 min/km pace equals 12 km/h; 6 mph equals a pace of 10:00 min/mile.
