Power to Weight Ratio Calculator

watts
choose unit
Outputs: watts per kilogram (W/kg). If weight entered in pounds, it is converted to kg first.

Use our Power to Weight Ratio Calculator to quickly find how much power is produced per unit of body weight. Enter the power value in watts and your weight in kilograms or pounds. If pounds are selected, the calculator automatically converts them to kilograms.

The result is displayed in watts per kilogram (W/kg), with an additional conversion into horsepower per metric ton (hp/ton) for reference. This tool is useful for cyclists, athletes, and vehicle performance analysis.

Formula Used:

  • Watts per kilogram (W/kg) = Power (W) ÷ Weight (kg)
  • Horsepower per ton (hp/ton) = (Power ÷ 745.7) ÷ (Weight ÷ 1000)
