How it's calculated
Pace is time divided by distance, written as minutes and seconds per kilometer or mile: 25 minutes over 5 km is 300 seconds per km, which is 5:00, and 5:00 per km is 8:03 per mile because a mile is 1.609344 km. Turned around, finish time is distance times pace, and distance is time divided by pace. The tool keeps everything in seconds, then splits the result into minutes and seconds with a floor and a remainder, which is why the two parts sit in separate boxes.
What is a good 5K pace?
A first 5K often lands between 10 and 13 minutes per mile (6:15–8:00 per km), a 30-minute 5K is 9:39 per mile, 25 minutes is 8:03, and 20 minutes, a strong club runner, is 6:26. The world records are around 4:00 per mile.
How do I convert pace per km to pace per mile?
Multiply by 1.609344: 5:00 per km is 300 seconds × 1.609 = 483 seconds, 8:03 per mile. Going the other way, divide. The tool shows both whenever you ask for pace.
What pace do I need to break 4 hours in a marathon?
Switch to "Pace", enter 42.195 km (or 26.2188 miles) and 3:59:59: just under 5:41 per km, 9:09 per mile. For a half marathon under 2 hours it is 5:41 per km as well, since a half is exactly half the distance in half the time.
