Enter the total number of seconds it takes to fill a 1-gallon container into the calculator to determine the gallons per minute.

GPM Formula

The following formula is used to calculate gallons per minute.

GPM = 60 / X
  • Where GPM is the gallons per minute
  • X is the number of seconds it takes to fill one gallon

To calculate gallons per minute, simply divide 60 by the number of seconds it takes to fill one gallon.

GPM Definition

GPM is defined as the rate of flow of water in gallons per minute.


GPM Example

How to calculate GPM?

  1. First, gather a 1 gallon bucket.

    Place the gallon bucket under the water flow.

  2. Next, measure the time it takes to fill.

    Using a stop watch, measure the time it takes to fill the bucket.

  3. Finally, calculate GPM.

    Calculate the GPM using the formula above and the seconds from step 2.
