Power-to-Weight Ratio Calculator
Use the Power-to-Weight Ratio Calculator to evaluate your strength or speed performance relative to your body weight. Whether you're a cyclist, runner, or powerlifter, this tool helps you understand how efficiently you convert weight into power or force. Ideal for performance analysis and competition comparison.
Strength or Speed Output per Body Weight
Power-to-Weight Ratio Formula
$$\text{PWR} = \frac{L}{BW}$$
Where:
- $$L$$ = Load lifted (kg or watts for power)
- $$BW$$ = Body weight (kg)
- Result in kg/kg or W/kg depending on context
Example
If a cyclist produces 300 watts and weighs 75 kg:
$$PWR = 300÷75=4.0 W/kg$$
The power-to-weight ratio (PWR) is a key metric in both strength sports and endurance disciplines like cycling and running.
- In strength training, it reflects how much weight you can lift per kg of body mass.
- In endurance sports, it’s usually calculated in watts per kilogram (W/kg) to assess performance on climbs and sprints.
Higher PWR means more efficient performance — an essential measure for athletes aiming to maximize output without unnecessary body mass.
