Frequently asked questions
What is 5:00 per km in minutes per mile?
8:03 per mile. Multiply the pace per km by 1.609344: 300 seconds × 1.609344 = 482.8 seconds, which rounds to 8:03. On a treadmill that’s 12.0 km/h or 7.5 mph.
What is an 8-minute mile in min/km?
4:58 per km (480 ÷ 1.609344 = 298.3 seconds). A 9-minute mile is 5:36 per km, and a 10-minute mile is 6:13.
How do I convert my pace to a treadmill speed in mph?
Divide 60 by your pace per mile in minutes. An 8:00 mile is 60 ÷ 8 = 7.5 mph; a 10:00 mile is 6.0 mph. Most treadmills step in 0.1 mph, so round to the closest setting.
Why is my converted pace a second off other charts?
Rounding. Some charts use 1.6 or 1.61 km per mile, or chop the seconds off. This tool uses 1.609344 and rounds once, to the nearest second, so 4:59.6 shows as 5:00, not 4:60.
How many miles is a half marathon and a marathon?
A half is 21.0975 km, or 13.11 miles. A marathon is 42.195 km, or 26.22 miles (26 miles 385 yards).
