WHP to HP Calculator - Understanding Power Loss

The WHP to HP Calculator helps you convert wheel horsepower (WHP) to engine horsepower (HP) by accounting for drivetrain losses. This is essential for understanding the actual power output of your engine versus what reaches the wheels.

How Does Drivetrain Loss Work?

When an engine produces power, not all of it reaches the wheels due to friction and mechanical losses in the drivetrain components:

  • Front-Wheel Drive (FWD): Typically loses 12-18% of power (average 15%)
  • Rear-Wheel Drive (RWD): Usually loses 15-20% of power (average 18%)
  • All-Wheel Drive (AWD): Generally loses 18-25% of power (average 20%)
  • Heavy Duty AWD: Can lose 20-30% of power (average 25%)

How to Use This Calculator?

Converting between WHP and HP is simple with our calculator:

  • Step 1: Select your vehicle's drivetrain type from the dropdown menu
  • Step 2: Choose conversion direction (WHP to HP or HP to WHP)
  • Step 3: Enter the power value you want to convert
  • Step 4: Click "Convert" to see the result with the formula breakdown
