Pace Converter

Pace is the time it takes to cover a distance, such as minutes per kilometer or per mile. It is the inverse of speed: a faster runner has a higher speed but a lower pace. This converter turns a pace into the other paces runners and swimmers use, and into speed in m/s, km/h and mph.

Paces are entered as decimal minutes. A pace of 5:30 per km is 5.5, since 30 seconds is half a minute, and 4:45 is 4.75. To turn a result back into minutes and seconds, multiply the decimal part by 60: 8.85 min/mi is 8 minutes and 0.85 × 60 = 51 seconds, or 8:51.

How to convert pace

1. min/km to min/mi: multiply by 1.60934, the kilometers in a mile.

   5.5 × 1.60934 = 8.851 min/mi, which is 8:51 per mile

2. Pace to speed: divide 60 by the pace in minutes.

   60 / 5.5 = 10.91 km/h

3. Speed to pace: divide 60 by the speed. For 12 km/h:

   60 / 12 = 5 min/km, or 5:00 per km

A 5 km race at 5:00 per km takes 25 minutes, and a marathon (42.195 km) at the same pace about 3 hours 31 minutes.

Speed and pace units

• Meters/Second (m/s): Meters per second is an internationally recognized unit that represents the distance covered in meters over one second.
  Conversion factor: 1 m/s = 3.6 km/h = 2.2369 mi/h

• Kilometers/Hour (km/h): Kilometers per hour measures the distance covered in kilometers over one hour, a common unit in international sports.
  Conversion factor: 1 km/h = 0.6214 mi/h = 0.2778 m/s

• Miles/Hour (mi/h): Miles per hour represents the distance covered in miles over one hour, a widely used unit in the United States and other countries using Imperial units of measurement.
  Conversion factor: 1 mi/h = 1.6093 km/h = 0.447 m/s

• Seconds per Meter (s/m): Seconds per meter indicates the time taken to cover one meter, with lower values representing faster paces.
  Conversion factor: 1 s/m = 100 s/100m

• Seconds per 100m (s/100m): Seconds per 100 meters measures the time taken to cover 100 meters, commonly used in track and field.
  Conversion factor: 1 s/100m = 0.01 s/m

• Seconds per Yard (s/yd): Seconds per yard measures the time taken to cover one yard, with smaller values indicating faster paces.
  Conversion factor: 1 s/yd = 100 s/100yd = 1.0936 s/m

• Seconds per 100yd (s/100yd): Seconds per 100 yards measures the time taken to cover 100 yards, frequently used in swimming.
  Conversion factor: 1 s/100yd = 0.01 s/yd = 1.0936 s/100m

• Minutes per Kilometer (min/km): Minutes per kilometer represents the time taken to complete one kilometer, with smaller values indicating faster paces.
  Conversion factor: 1 min/km = 1.60934 min/mi = 0.06 s/m

• Minutes per Mile (min/mi): Minutes per mile measures the time taken to complete one mile, with smaller values indicating faster paces.
  Conversion factor: 1 min/mi = 0.6214 min/km = 0.03409 s/yd

Frequently asked questions

How do I convert a swimming pace per 100 m to per 100 yd?

Multiply by 0.9144, since 100 yards is 91.44 meters. A pace of 1:40 per 100 m (100 seconds) is 100 × 0.9144 = 91.4 seconds per 100 yd, or 1:31.
