Common questions
What speed is 6:00 per kilometre?
10 km/h, or about 6.21 mph. That is approximately 9:39 per mile.
How should I use the result?
Pace and speed are inverse measures: a smaller pace number means a higher speed. Rounding to whole seconds can produce small differences when converting back.
