Why Use a Running Pace & Speed Converter?#
Different countries, treadmill consoles, and GPS running watches display running intensity using different units. While runners in most of the world use minutes per kilometre (min/km), runners in the US and UK often use minutes per mile (min/mi). Treadmills and indoor exercise bikes usually report speed in kilometres per hour (km/h) or miles per hour (mph).
Our interactive running pace converter lets you instantly toggle between pace and speed formats, making it easy to translate your training targets across treadmills, watches, and race plan guides.
Key Running Unit Conversions#
Here is a quick reference formula for common unit conversions used by runners:
- Pace (min/km) to Pace (min/mi):
Pace (min/mi) = Pace (min/km) × 1.60934 - Pace (min/km) to Speed (km/h):
Speed (km/h) = 60 ÷ Pace (min/km in decimal) - Speed (km/h) to Speed (mph):
Speed (mph) = Speed (km/h) ÷ 1.60934
