Pace ↔ speed converter

Pace ↔ speed conversion explained

Pace and speed are the two complementary languages of running. Pace in min/km is intuitive on a watch (lower = faster). Speed in km/h matches treadmills, cycling and your car. This converter lets you go from one to the other instantly.

Practical conversion examples

• 5:00/km = 12.0 km/h = 7.5 mph (typical marathon pace 3h30)
• 4:30/km = 13.3 km/h = 8.3 mph (sub-3h marathon territory)
• 6:00/km = 10.0 km/h = 6.2 mph (beginner / long run)

Imperial vs metric

Many U.S. and U.K. apps and watches use min/mile and mph. To convert km → mile, multiply by 0.621. To convert pace/km → pace/mile, multiply by 1.609.
