**Definitions:**

**US Gallon** (abbreviation: **US gal**): is a unit of measurement for liquid capacity in the US customary units. Three significantly different sizes are in current use: the imperial gallon defined as 4.54609 litres, which is used in the United Kingdom, Canada, and some Caribbean nations; the US gallon defined as 231 cubic inches (3.785 L), which is used in the US and some Latin American and Caribbean countries; and the least-used US dry gallon defined as 1/8 US bushel (4.405 L).

**Liter** (abbreviations: **ltr, or lit, or l, or litre**): is an SI accepted metric system unit of volume equal to 1 cubic decimetre (dm3), 1,000 cubic centimetres (cm3) or 1/1,000 cubic metre. A cubic decimetre (or litre) occupies a volume of 10x10x10 centimetres and is thus equal to one-thousandth of a cubic metre.

## How to Convert US Gallons to Liters

*Example: How many liters are equivalent to 45.69 US gallons?*

As;

1 US gallons = 3.79 liters

45.69 US gallons = Y liters

Assuming Y is the answer, and by criss-cross principle;

Y equals 45.69 times 3.79 over 1

(i.e.) Y = 45.69 * 3.79 / 1 = 173.1651 liters

Answer is: 173.1651 liters are equivalent to 45.69 US gallons.
