What Is a Gallon?

In both the US customary and Imperial measurement systems, the gallon is a fundamental volume unit. Its definition has evolved over centuries; for instance, 18th‑century England used separate wine gallons and beer gallons, each with a different capacity. Today, two primary definitions are recognized:

Gallon type	Volume in liters	Common use
US liquid gallon	$3.785412\ \text{L}$	United States (most everyday measures)
Imperial gallon	$4.54609\ \text{L}$	United Kingdom and some Commonwealth countries

The US gallon is approximately 20 % smaller than its Imperial counterpart. The volume conversion calculator presented here relies on the US liquid gallon, which is the standard for most gallon‑to‑quart conversions in the United States.

What Is a Quart?

The word “quart” comes from the Latin quartus, meaning “a fourth part”—hinting at its relationship to the gallon. Like the gallon, the quart has several variations:

US liquid quart – $0.946353\ \text{L}$ (equal to $1/4$ US gal)
US dry quart – $1.101221\ \text{L}$ (about $0.29$ US gal)
Imperial quart – $1.136523\ \text{L}$ (about $0.30$ Imp gal)

This online converter uses the US liquid quart, ensuring consistency with the US liquid gallon.

How to Convert Gallons to Quarts

The conversion between these two US customary units is linear and easy to remember:

1\ \text{US gallon} = 4\ \text{US quarts}

Therefore, to perform a gallons to quarts online conversion:

\text{quarts} = \text{gallons} \times 4

For example:

$0.5$ gallon $=$ $2$ quarts (a half‑gallon equals two quarts)
$1$ gallon $=$ $4$ quarts
$3$ gallons $=$ $12$ quarts
$5$ gallons $=$ $20$ quarts

To go in the opposite direction—quarts back to gallons—simply divide the number of quarts by $4$ .
