Cycling Power Output Calculator
Cycling Power Output Calculator is a health and wellness calculator that helps you calculate the power output in watts needed for cycling based on speed, gradient and rider weight. The formula used is: P_total = P_rolling + P_gradient + P_aero. P_aero = 0.5 × ρ × CdA × v_rel² × v_speed.. Enter values using the units shown next to each input field (e.g. kg, cm, years).
Formula
P_total = P_rolling + P_gradient + P_aero. P_aero = 0.5 × ρ × CdA × v_rel² × v_speed.
Example Calculation
Inputs
- Speed: 30 km/h
- Rider + Bike Weight: 75 kg
- Gradient: 0 %
- Headwind Speed: 0 km/h
Suppose you enter: Speed = 30, Rider + Bike Weight = 75, Gradient = 0, Headwind Speed = 0. The calculator applies the formula (P_total = P_rolling + P_gradient + P_aero. P_aero = 0.5 × ρ × CdA × v_rel² × v_speed.) and shows all output values below. Change any input field to immediately see how the result changes.
