Enter the horsepower (hp) into the calculator. The calculator will evaluate the Gph given the horsepower.

Hp To Gph Formula

GPH = HP /10


  • GPH is the Hp To Gph (gallons per hour)
  • HP is the horsepower (hp)

To calculate gallons per hour from horsepower, simply divide the horsepower by 10.

How to Calculate Hp To Gph?

The following steps outline how to calculate the Hp To Gph.

  1. First, determine the horsepower (hp). 
  2. Next, gather the formula from above = GPH = HP /10.
  3. Finally, calculate the Hp To Gph.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
