Convert between min/km, min/mi, km/h, and mph. See equivalent race times at common distances.
Converting pace between min/km and min/mi seems trivial - just multiply or divide by 1.609 - but understanding the physiological implications matters more than the arithmetic.
Why both units exist: Most of the world trains in min/km; the US and UK typically use min/mi. GPS watches default to your region setting, but race pace charts, coaching plans, and online communities mix both. Converting manually leads to errors - rounding 4:30/km to 7:14/mi is easy; remembering that 7:30/mi = 4:39/km is not.
Speed vs. pace: Speed (km/h or mph) is linear - a 1 km/h increase is the same change at any speed. Pace (min/km) is hyperbolic - going from 6:00/km to 5:30/km (a 0.5 km/h gain at slow speeds) is much easier than going from 4:00/km to 3:38/km (the same 0.5 km/h gain at fast speeds). This is why "negative splits" are harder than they sound.
Race-time equivalents at constant pace are a starting point, not a promise. The pace you can hold for 5K is not the same pace you can hold for a marathon - the fatigue-resistance assumption here is zero. Use the race-time equivalents to understand the magnitude of each distance.
Baseline automatically normalises your pace data from any device - whether it sends min/km, min/mi, km/h, or mph - so your trends are always comparable. We also track your actual pace-decay curve from your real activities, which is more useful than any generic conversion table.
