How to convert min/mile to min/km manually
- Convert your pace to total seconds. Example: 8:00 /mile = 8 × 60 = 480 seconds per mile.
- Divide by 1.609, the number of kilometres in a mile. 480 ÷ 1.609 ≈ 298 seconds per kilometre.
- Convert back to minutes and seconds. 298 ÷ 60 = 4 minutes, remainder 58 seconds, so 4:58 /km.
Shortcut formula: min/km = min/mile ÷ 1.609 and min/mile = min/km × 1.609.

- Sub-2-hour half marathon — ~9:09 /mile, ~5:41 /km (same pace as sub-4 marathon).
- Sub-25-minute 5k — ~8:02 /mile, ~5:00 /km.
- Sub-50-minute 10k — ~8:03 /mile, ~5:00 /km.
