Our GPM Calculator is a user-friendly tool that determines how many gallons of liquid (usually water) flow through a system or device every minute/hour. It's used to measure flow rates for various applications, like plumbing or irrigation, and help you understand how fast liquid moves in fluid-related equipment.

## Steps to Use GPM Calculator:

Using a gallons per minute calculator is straightforward and you can save __time__ and effort when you need to know the flow rate of a fluid. To make the most out of it, let’s go through these easy steps to use the GPM Calculator effectively.

**What to Enter?**

**Step 1:**First, Choose the units in which you want to calculate**Step 2:**Then, Enter all the values into their selected field**Step 3:**Press the Calculate button

**What will you get?**

- The exact flow rate for the selected unit

## The formula of GPM:

Here is the basic GPM formula that our GPM calculator uses to help you calculate the GPM flow rate.

**$$ \Large GPM = \frac{Volume}{Time} $$**

## How to Calculate GPM?

If you want to calculate GPM manually, we will illustrate an example to help you understand better. You can also try our free gallons per __hour__ calculator for this purpose.

### Example:

Imagine you are filling up a swimming pool and want to know the flow rate, or GPM, of the water coming out of your garden hose. You have measured the volume of water and the time it takes to fill the pool.

**Data:**

- The volume of water used: 1000 gallons
- The time it takes to fill the pool: 20 minutes

Now, we'll use the GPM formula to find the flow rate:

$$ GPM = \frac{Volume}{Time} $$

$$ GPM = \frac{1000\; gallons}{20\; minutes} $$

$$ GPM = 50\;gallons\;per\;minute $$

So, in this scenario, the flow rate of the water coming out of your garden hose is 50 Gallons Per Minute (GPM). This means that your hose delivers 50 gallons of water every minute.

Understanding this number is useful for many things, like knowing how much __water__ you have and making sure you use it wisely.

## FAQs:

### What is GPM?

GPM, which stands for Gallons Per Minute, is a unit of measurement used to indicate how quickly a liquid (typically water) flows from one place to another in a single minute is called GPM. It is also known as flow rate.

### How Many Gallons per Minute Does a Shower Use?

The number of gallon per minute (GPM) a shower uses can vary, but on average, a typical shower uses around 2.5 gallons per minute. However, some showers may use more or less water depending on factors like water pressure and the type of showerhead.

### Can I use the GPM Calculator for different liquids?

Yes, The GPM Calculator is versatile and can be used for various liquids, whether it’s water, oil, or any other fluid.
