Enter the length, width, and height of the aquarium into the calculator to determine the total gallons of water it can hold. This calculator can also evaluate any of the variables given the others are known.

## Aquarium Gallons Formula

The following formula is used to calculate the gallons of water an aquarium can hold.

G = L * W * H * 0.004329

Variables:

- G is the total gallons of water the aquarium can holdL is the length of the aquarium (inches) W is the width of the aquarium (inches) H is the height of the aquarium (inches)

To calculate the gallons of water an aquarium can hold, multiply the length of the aquarium by the width and then by the height. Multiply the result by 0.004329 to convert cubic inches to gallons.

## What is an Aquarium Gallons?

Aquarium gallons refer to the capacity or size of an aquarium, measured in gallons. It indicates the amount of water the aquarium can hold. The size of the aquarium is crucial as it determines the number and type of aquatic creatures it can accommodate. Larger aquariums can support more fish and provide a more stable environment, while smaller ones may require more maintenance and careful monitoring.

## How to Calculate Aquarium Gallons?

The following steps outline how to calculate the total gallons of water an aquarium can hold using the given formula:

- First, determine the length of the aquarium (L) in inches.
- Next, determine the width of the aquarium (W) in inches.
- Next, determine the height of the aquarium (H) in inches.
- Next, multiply the length (L), width (W), and height (H) of the aquarium together.
- Finally, multiply the result by the conversion factor 0.004329 to calculate the total gallons of water (G) the aquarium can hold.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Length of the aquarium (L) = 20 inches

Width of the aquarium (W) = 12 inches

Height of the aquarium (H) = 16 inches
