Calculation Formula

Power to Weight Ratio:

HP per Pound = Horsepower ÷ Vehicle Weight (lbs)

Weight to Power Ratio:

Pounds per HP = Vehicle Weight (lbs) ÷ Horsepower

注意: Power to weight ratio is a key indicator of vehicle performance. Higher ratios generally mean better acceleration and performance, but other factors like aerodynamics, traction, and gearing also play important roles.
