Convert pints to gallons and back. US and imperial systems, gallon-jug fill visualization, volume hierarchy table, and extended reference chart.
There are 8 pints in a gallon in both the US and imperial systems, but the size of the pint changes with the system. A US pint is about 473 mL, while an imperial pint is about 568 mL, so the same pint count can represent very different liquid volumes. That means you can get the right number of pints and still end up with the wrong total volume if you do not keep the system consistent from the start.
This converter handles pints-to-gallons and gallons-to-pints in both systems and shows the result in quarts, cups, fluid ounces, milliliters, and liters. The gallon-fill visual is useful when you are scaling drink recipes, planning a homebrew batch, or checking how many containers you need. It also makes fractional gallon amounts easier to interpret because you can see how much of the jug is actually filled instead of guessing from a decimal.
Use it when you need fast volume math without mixing US and UK measures. The companion units keep the result practical for kitchen work, batch planning, and container sizing.
Pints and gallons are closely related, but the US and imperial systems are easy to mix up. This converter keeps the unit system explicit, converts to the most useful companion units, and makes partial-gallon amounts easier to picture. It is especially handy when a batch size or container capacity is written in one system and you need to compare it with another quickly.
US: 1 gallon = 8 pints = 4 quarts = 128 fl oz = 3,785.41 mL Imperial: 1 gallon = 8 pints = 4 quarts = 160 fl oz = 4,546.09 mL
Result: 1.5 gallons = 6 quarts = 5,677.6 mL
12 pints ÷ 8 = 1.5 US gallons. That's 6 quarts, 24 cups, or 5.68 liters.
US customary volume follows a clean 2× progression: 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon. This means 1 gallon = 8 pints = 16 cups = 128 fl oz. Once you memorize the "2-2-4" pattern, you can do all conversions mentally.
Standard homebrew recipes target 5 gallons (40 pints / 18.93 liters). Smaller "kitchen" batches are typically 1 gallon (8 pints). Commercial keg sizes: a US half-barrel (standard keg) = 15.5 gallons = 124 pints; a "pony" keg = 7.75 gallons = 62 pints.
Caterers scale recipes from servings to gallons. A pot of soup at 6 oz per serving and 50 guests needs 300 fl oz = about 2.34 gallons = 18.75 pints. Having the pint-to-gallon conversion memorized speeds up kitchen planning.
8 pints in a gallon in both systems. The difference is that a US pint and an imperial pint are not the same size, so the volume behind the count changes.
4 pints. That is true in both the US and imperial systems, so the count is stable even though the pint size changes.
Yes. A US gallon is 3,785 mL while an imperial gallon is 4,546 mL. The imperial gallon is about 20 % larger.
US: 3.785 liters. Imperial: 4.546 liters. The answer depends on which gallon system you are using.
40 US pints. A standard 5-gallon batch is also about 18.9 liters, which helps when comparing recipe notes from different sources.
Divide pints by 2. So 6 pints = 3 quarts, and the same rule works in reverse when you need to convert quarts back to pints.
