Convert pace per mile to pace per km and back. Instantly see your running speed in mph and km/h.
This mile pace calculator instantly converts running pace between minutes-per-mile and minutes-per-kilometer, and shows your equivalent speed in mph and km/h. It also includes a full reference conversion table covering every common pace from 4:30/mile (elite) to 15:30/mile (brisk walk).
The USA, UK, and parts of the Caribbean use miles for road racing — most GPS watches, race signs, and training plans in these countries express pace as min/mile. Runners in Europe, Asia, Australia, and most of the rest of the world use km. This tool bridges the gap instantly, so you always know exactly what your pace means in both systems.
Common use cases: Converting a training plan written in miles to your GPS watch set to km; understanding your race splits when the course markers are in miles but your watch shows km; comparing personal records from different countries; and setting pace zones for heart-rate-based training.
Multiply your pace per mile by 0.621371 to get pace per km. For example, 8:00/mile × 0.621371 = 4:58/km. Alternatively, divide your pace per mile (in seconds) by 1.60934 to get seconds per km, then convert back to minutes:seconds.
An 8:00/mile pace equals approximately 4:58/km. This is a strong recreational running pace that equates to a speed of 7.5 mph (12.1 km/h). At this pace you'd finish a 5K in 24:51 and a 10K in 49:42.
A 5:00/km pace equals approximately 8:03/mile. This is a solid training and racing pace for many runners, equivalent to 12 km/h (7.46 mph). At this pace you'd finish a 5K in 25:00 and a 10K in 50:00.
A 6:00/mile pace equals 3:44/km, or 10 mph (16.1 km/h). This is a fast pace — most recreational runners cannot sustain this for a full 5K. At this pace you'd finish a 5K in 18:39 and a 10K in 37:17.
If your watch says your mile splits are “off” on a track, don’t force your pacing plan to match the GPS number. In 2026, most watches still drift on 400 m tracks, especially in lanes 2+ and near stadium structures. For mile-pace workouts, use track distance or your watch’s track mode, then compare lap pace after the session. A common mistake is speeding up mid-rep because the watch shows 6:55 instead of 7:00 pace, which turns controlled intervals into accidental overtraining.
