Pace Calculator
Enter a distance in kilometers and the time it took to find your pace and speed.
How pace and speed are calculated
Pace is time divided by distance, usually expressed as minutes and seconds per kilometer or mile — a lower pace number means you're moving faster. Speed is the inverse relationship: distance divided by time, usually expressed in km/h or mph.
This calculator converts between kilometers and miles using the exact factor 1 mile = 1.609344 kilometers, so your pace and speed are shown correctly in both unit systems regardless of which you entered your distance in.
Frequently asked questions
How do I convert a 5:00 min/km pace to min/mile?
Multiply the min/km pace by 1.609344 (the number of kilometers in a mile): 5:00 × 1.609344 ≈ 8:03 min/mile.
What's a good running pace?
This varies enormously by fitness level, goal, and distance — this calculator just converts your actual pace between units, it doesn't evaluate whether a pace is "good."
How do I calculate my finish time for a race at a given pace?
Multiply your pace (minutes per km or mile) by the race distance in that same unit — for example, a 5:00/km pace over a 10K distance gives a 50:00 finish time.
