Minutes to Miles Per Hour Formula

mph = 60 ÷ M
mphSpeed in miles per hour
MMinutes taken to cover one mile, with seconds counted as a fraction: 7 min 30 s is 7.5

An hour has 60 minutes, so the number of miles covered in an hour is 60 divided by the minutes each mile takes.

Speed from pace

The formula applies directly: an 8 minute mile is 60 ÷ 8 = 7.5 mph, and a 10:30 mile is 60 ÷ 10.5 = 5.71 mph. For a pace per kilometer, the result is also divided by 1.609344, the kilometers in a mile [1]: 5:00 per kilometer is 60 ÷ 5 ÷ 1.609344 = 7.46 mph.

Pace from speed

M = 60 ÷ mph

7.5 mph is 60 ÷ 7.5 = 8 minutes per mile. 6.5 mph is 9.23 minutes, shown as 9:14 because the pace is rounded to the nearest second. A speed in km/h is divided by 1.609344 first, so 12 km/h is 7.46 mph, or 8:03 per mile.

Average speed

mph = d ÷ t

d is the distance in miles and t is the elapsed time in hours. A 49 mile trip that takes 2 hours 21 minutes averages 49 ÷ 2.35 = 20.85 mph. Walking 2.5 miles in 54 minutes averages 2.5 ÷ 0.9 = 2.78 mph, a pace of 21:36 per mile.

How Many Miles Is 30 Minutes?

Minutes turn into miles only once a speed is known: miles = mph × minutes ÷ 60. Thirty minutes is 1.5 miles at a 3 mph walk, 3 miles at a 6 mph run, 15 miles at 30 mph and 30 miles at 60 mph. To find the speed for a trip already made, use the Average speed function.

Limits of This Estimate

  • The result is an average. Speed during a run, walk or drive rises and falls, so the pace at any one moment can differ from the figure shown.
  • Pace clocks are rounded to the nearest second, while the mph figure keeps six decimal places. Converting a rounded pace back to speed can differ in the last decimals.
  • Stops count. Time spent at lights or resting lowers an average speed unless it is left out of the elapsed time.
