How does this calculator work?
1 gallon = 8 pints = 4 quarts = 16 cups (for both US and Imperial). The US pint ≈ 473 mL (16 fl oz); the Imperial pint ≈ 568 mL (20 fl oz) — about 20% larger. Divide pints by 8 to get gallons. Never mix US and Imperial units in the same calculation.
Formula
How this is calculated
Both the US customary and Imperial measurement systems divide a gallon into exactly 8 pints, 4 quarts and 16 cups — the integer ratios are identical. The difference lies in the underlying volume of a fluid ounce: the US fluid ounce equals about 29.57 mL, while the Imperial fluid ounce equals about 28.41 mL. This means a US pint (16 US fl oz ≈ 473 mL) is smaller than an Imperial pint (20 Imperial fl oz ≈ 568 mL), even though both are "one-eighth of a gallon."
In practice, a US pint glass holds 16 fl oz ≈ 473 mL, while a UK pint (used for beer in British pubs) holds 20 Imperial fl oz ≈ 568 mL — about 20% more liquid. This is a common source of confusion when comparing beer volumes or recipes across the two systems.
The conversion ratios used here are exact by statutory definition. Litres are computed using the exact millilitre equivalents: 1 US liquid gallon = 3,785.411784 mL and 1 Imperial gallon = 4,546.09 mL (defined by the Weights and Measures Act).
Frequently asked questions
Both the US liquid gallon and the Imperial gallon divide into exactly 8 pints. However, a US pint ≈ 473 mL (16 US fl oz) and an Imperial pint ≈ 568 mL (20 Imperial fl oz) — the Imperial pint is about 20% larger.
Both are defined as 1/8 of their respective gallons, but the Imperial gallon (4,546 mL) is about 20% larger than the US liquid gallon (3,785 mL). So a UK pint ≈ 568 mL and a US pint ≈ 473 mL. A UK pub pint of beer is therefore about 95 mL more than a US pint.
Divide pints by 8 for either system: 8 pints = 1 gallon. So 12 US pints = 1.5 US gallons; 20 Imperial pints = 2.5 Imperial gallons. Never mix US and Imperial values in the same calculation.
