計算自行車功率(瓦特)

Rider weight (kg)

Bike + equipment (kg)

Ground speed (km/h)

Gradient (%)

Headwind (km/h; tailwind negative)

Rolling coefficient Crr

CdA (m²)

Physics estimate assuming air density 1.225 kg/m³ and 97% drivetrain efficiency. Road, position, altitude, acceleration and wind cause differences from a power meter; braking/inertia on descents are not modeled.
