## What is a Gallon?

A gallon is a unit of volume widely used in the United States. For our purposes, we’ll focus on US gallons. There are three types in use: the Imperial gallon (UK gallon), the US gallon, and the US dry gallon. In this discussion, we’ll concentrate on the US gallon, denoted as *USgal*.

## How Many Gallons in One Square Foot?

There are 7.48052 gallons in one cubic foot. To understand how many gallons are in one square foot, consider a cuboid with a base area 2*Aft*2 and a height *Hft*. The volume in gallons (*VolinUSgal*) for one square foot is given by 3*H*×7.48052*USgal*/*ft*3.

In summary, the volume in gallons per square foot depends on the object’s height and is calculated as 3*H*×7.48052*USgal*/*ft*3.

## How Many Square Feet in a Gallon?

One US gallon equals 0.133681 cubic feet. Using this conversion rate, the volume in cubic feet (3*Volinft*3) for a given gallon is 3*H*×0.133681*ft*3.

## Calculating Gallons of Water per Square Foot

For calculating the gallons of water (*Volwater*) in one square foot of a container with height *H*, use the formula*Volwater*=*H*×7.48052, where 7.48052 is the conversion rate from cubic feet to gallons.

This concept is applicable to any liquid, not just water.
