How the Speed-to-Pace Converter Works
Pace inverts speed: dividing 60 minutes by your km/h gives minutes per kilometre, and multiplying by 1.609 converts to minutes per mile since a mile is 1.609 km. The finish time multiplies pace by your race distance — at 12 km/h (5:00 min/km) a 10 K takes 50 minutes and a marathon about 3:30. Coaches quote pace because it stays constant across training zones, while speedometers and treadmills speak km/h.
