Pace to speed converter

Switch between a running pace in min/mi and a speed in mph, km/h or m/s, in both directions. Handy for comparing your road pace, reading a treadmill in mph or decoding a plan written in kilometers. Instant conversion, both ways.

Pace per kilometer

One mile is 1.609344 km. Pace (min/mi) and speed (mph) are inverses of each other: the faster you run, the lower your time per mile.

How to convert pace and speed

Your pace (the time it takes to cover a mile, in min/mi) and your speed (the distance covered in an hour, in mph) describe the same effort in two inverse ways. One division takes you from one to the other:

speed (mph) = 60 ÷ pace (min/mi)   and   pace (min/mi) = 60 ÷ speed (mph)

Example: a pace of 8:00/mi is 8.0 minutes per mile, so 60 ÷ 8 = 7.5 mph. Conversely, 7.5 mph gives 60 ÷ 7.5 = 8.0 minutes, or 8:00/mi.

Speed in km/h and m/s

Once you know your speed in mph, the other units follow directly:

km/h = mph × 1.609344   |   m/s = km/h ÷ 3.6

Example at 7.5 mph: 7.5 × 1.609344 = 12.07 km/h and 12.07 ÷ 3.6 = 3.35 m/s. The 1.609344 factor is simply the length of one mile in kilometers.

Pace per kilometer

To turn a pace per mile into a pace per kilometer, divide by the length of a mile in km:

pace (min/km) = pace (min/mi) ÷ 1.609344

Example: a pace of 8:00/mi (8.0 minutes) becomes 8 ÷ 1.609344 = 4.97 minutes, about 4:58 per kilometer. That’s the pace you’ll see on a watch set to metric units or at a race marked in kilometers.

Benchmarks: 10:00/mi equals 6 mph, and 8:00/mi equals 7.5 mph. For a pace per kilometer, divide the pace per mile by 1.609344.

Frequently asked questions

How do I convert a pace in min/mi into a speed in mph?

Divide 60 by your pace in decimal minutes. A pace of 8:00/mi is 8.0 minutes per mile, so 60 ÷ 8 = 7.5 mph. A pace of 10:00/mi gives 60 ÷ 10 = 6 mph. The other way round, to go from a speed to a pace, calculate 60 ÷ speed: 7.5 mph gives 60 ÷ 7.5 = 8 minutes per mile, or 8:00/mi.

How do I convert mph to km/h?

Multiply your speed in mph by 1.609344 (one mile is 1.609344 km). For example, 7.5 mph is 7.5 × 1.609344 = 12.07 km/h. The other way, multiply km/h by 0.621371 to get mph.

How do I get my speed in m/s?

Convert to km/h first, then divide by 3.6: 7.5 mph is 12.07 km/h, or 12.07 ÷ 3.6 = 3.35 m/s. It comes in handy for physics calculations or stage tests expressed in meters per second.

How do I convert a pace per mile into a pace per kilometer?

Divide your pace in min/mi by 1.609344, since a mile is 1.609344 km. A pace of 8:00/mi (8.0 minutes) becomes 8 ÷ 1.609344 = 4.97 minutes, about 4:58 per kilometer. Useful for races marked in kilometers or plans written in metric units.

Pace or speed: which should I train with?

Both describe the same thing, but pace in min/mi is more intuitive on the road and the track (you think in time per mile), while speed in mph is more practical on a treadmill and for stage tests. This converter switches between the two instantly, whatever tool you’re using.
