mile pace and finish time calculator
The mile is 1609.344 metres — 1.609 km, or 1.000 miles. Enter a pace and this gives the finish time, or work backwards from a target. The mile is exactly 1609.344 metres by the 1959 international agreement.

Show the working
- Pace, minutes per km = 4.5
- Plus seconds = 0
- Or a target time, hours = 0
- Target minutes = 0
- distance_m = 1609.344 = 1609.34
- distance_km = 1609.34 / 1000 = 1.609 34
- Pace per kilometre = 4.5 * 60 + 0 = 270
- Finish time = 270 * 1.609 34 = 434.523
- Speed = 270 > 0 ? 3600 / 270 : 0 = 13.3333
- Speed in metres per second = 13.3333 / 3.6 = 3.7037
- Pace per mile = 270 * 1.609344 = 434.523
- target_seconds = 0 * 3600 + 0 * 60 = 0
- Pace needed for the target time = 1.609 34 > 0 && 0 > 0 ? 0 / 1.609 34 : 0 = 0
- Halfway split = 434.523 / 2 = 217.261
- Quarter split = 434.523 / 4 = 108.631
- Pace per 400 m lap = 270 * 0.4 = 108
- Track laps = 1609.34 / 400 = 4.023 36
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- finish time = pace per km x distance in km
- pace per mile = pace per km x 1.609344
- speed in km/h = 3600 / pace in seconds per km
Splits assume an even pace. Most runners are better served by starting slightly slower than target and finishing faster.
The mile is exactly 1609.344 m, so the pace conversion here is exact rather than rounded.
The mile is exactly 1609.344 metres by the 1959 international agreement.
