Enter the total horsepower (hp) and the total mass (kg) into the Calculator. The calculator will evaluate the Hp To Kg Ratio. 

Hp To Kg Ratio Formula

HP:kg = Hp / kg


  • HP:kg is the Hp To Kg Ratio ()
  • Hp is the total horsepower (hp)
  • kg is the total mass (kg)

To calculate Hp To Kg Ratio, divide the horsepower by the mass in kilograms.

How to Calculate Hp To Kg Ratio?

The following steps outline how to calculate the Hp To Kg Ratio.

  1. First, determine the total horsepower (hp). 
  2. Next, determine the total mass (kg). 
  3. Next, gather the formula from above = HP:kg = Hp / kg.
  4. Finally, calculate the Hp To Kg Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total horsepower (hp) = 70

total mass (kg) = 54


What is horsepower (hp)?
Horsepower (hp) is a unit of measurement for power, which is the rate at which work is done. It is traditionally used to measure the power of engines and motors.

Why is the Hp to Kg ratio important?
The Hp to Kg ratio is important because it helps to determine the efficiency and performance of a vehicle or machine. A lower mass with higher horsepower generally indicates a better performance capability.

Can the Hp to Kg ratio be used for electric vehicles?
Yes, the Hp to Kg ratio can also be applied to electric vehicles. It is used to compare the power to weight ratio, which is a significant factor in determining the acceleration and efficiency of electric vehicles.

How can improving the Hp to Kg ratio benefit a vehicle?
Improving the Hp to Kg ratio, either by increasing horsepower or reducing mass, can lead to better acceleration, higher top speeds, and improved overall performance of a vehicle.
