Cycling Power Calculator
Know your cycling power output without a power meter.
How to Use This Tool
- Enter average speed in km/h.
- Select terrain type.
- Enter your rider weight.
- Get estimated watts and calories burned.
The Formula
Watts = (Speed / 30) × Terrain Factor × Weight. 1 watt ≈ 3.6 kcal/hour.
Why It Matters
You are cycling on flat terrain at 20 mph as a 175 lb rider. Your estimated power output is 180 watts (1.03 W/kg). Recreational cyclists average 1.5-2.0 W/kg, while professionals sustain 4-6 W/kg. You are in the casual-to-intermediate range.
