Pace Calculator
Turn a distance and a finish time into pace per kilometer or mile, plus average speed. Heart rate and elevation are not used.
How to use
- Type Distance and set Unit to km or miles. The sample distance is 5, and the sample unit is km.
- Enter the finish time in Hours, Minutes, and Seconds. The sample is 0 hours, 25 minutes, and 0 seconds. Minutes and seconds are intended to stay under 60.
- Press Calculate Pace. The sample is 25 minutes for 5 km, so the pace line reads 5:00 / km and the detail line reads Speed: 12.00 km/h.
- Switch Unit to miles if the distance is in miles. The pace suffix follows the selected unit value, so miles display as mi, for example 8:00 / mi. If distance or total time is zero or blank, the result says Enter distance and time.
When it helps
Check a workout after you know how far you went and how long it took. Use it to compare two races only by doing two separate calculations; the form holds one distance and one time.
The result is arithmetic from the distance and time you typed, not a diagnosis, a training plan, or a medical target. It does not estimate calories. For an intake or burn estimate, use the calorie calculator, which asks different questions. If you need to add two split times before you type a single finish time, total them on the hours calculator first.
Limits
Heart rate, elevation, grade, wind, and cadence are not inputs, and they do not change the pace. The speed is an average over the whole distance, not a current GPS reading and not a set of kilometer splits. There is no pace-to-finish predictor that asks for a goal time and returns a required pace as a separate mode; you can only reverse the arithmetic by trying numbers.
Unit offers km or miles only. A distance in meters must be converted before you type. Seconds in the pace are rounded, and a value that rounds to 60 can display as :60 instead of carrying into the next minute.
Questions
Does pace account for hills or heart rate?
No. Only Distance, Unit, Hours, Minutes, and Seconds are read. Elevation and heart rate are not on the form and are not estimated.
Why does miles show up as mi?
The Unit menu says miles, and the calculation uses the value mi on the pace line and on the speed line, as in 12.00 mi/h.
What if I leave time at zero?
Calculate Pace refuses the run and shows Enter distance and time. The same message appears when distance is zero. A pace cannot be divided from an empty effort.
