## 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

## GPM Definition

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

## GPM Example

How to calculate GPM?

**First, gather a 1 gallon bucket.**Place the gallon bucket under the water flow.

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

**Finally, calculate GPM.**Calculate the GPM using the formula above and the seconds from step 2.

## FAQ

**What is GPM?**

GPM stands for gallons per minute and is a measure of the volumetric flow rate of a liquid, most often water.
