Convert gallons to pints and pints to gallons for US and imperial systems. Includes quarts, cups, fluid ounces, liters, and container reference table.
One gallon contains 8 pints in both the US and imperial systems, but the pint itself is larger in the imperial system. That means the count is the same while the actual liquid volume changes, which matters in brewing, catering, and any recipe that crosses US and UK measurements. A brewery case study, a pub menu, or a recipe imported from overseas can all look identical on paper while actually holding different amounts of liquid. That is why the unit label matters just as much as the number.
This converter handles gallons-to-pints and pints-to-gallons in both systems and also shows quarts, cups, fluid ounces, liters, and milliliters. The extra unit outputs are useful when you need to move from batch size to serving size or container size without doing more conversions by hand. It is especially handy when you are comparing a US container to a UK one and need to know whether the bottle count or the actual volume changed. The side-by-side values make it easier to check serving counts or keg yields before you pour.
Use it when you need a direct gallon-pint answer and want to keep the US versus imperial difference visible. The extra context makes it easier to compare keg sizes, milk jugs, and recipe batches without mixing systems.
The ratio itself is simple, but the system difference is not. This page helps you avoid mixing US and imperial pints while also showing the surrounding units used in kitchens, bars, and brewing setups. It is the safer choice when a number needs to be reused in a menu, recipe, or container label.
1 US gallon = 8 US pints (each 473.176 mL) 1 Imperial gallon = 8 Imperial pints (each 568.261 mL)
Result: 40 US pints
5 × 8 = 40 US pints. That is also 20 quarts, 80 cups, or 18.927 liters—about the volume of a Cornelius keg.
Home brewers and craft breweries measure batches in gallons (usually 5-gallon batches) but serve in pints. Knowing that 5 gallons = 40 pints helps estimate how many servings a batch will yield. Commercial kegs are rated in gallons but marketed in pints—a half-barrel keg (15.5 gal) yields about 124 pint servings.
The UK legally requires draught beer to be served in imperial pints (568 mL). In the US, a "pint" at a bar is often a 16-oz (473 mL) glass, but there is no federal regulation—some bars serve 14-oz "shaker pints." When comparing prices per pint internationally, account for the 20 % size difference.
Half-gallon cartons of milk or juice contain exactly 4 US pints. When a recipe calls for "3 pints of stock," that is 1.5 quarts or 0.375 gallons—easy to measure from a gallon jug by filling to the halfway mark and then adding half again.
A gallon contains 8 pints in both US and imperial systems. The count is the same, but the pint volume changes depending on which system you are using.
A half gallon equals 4 pints. That is a simple shortcut that works in both systems because the gallon-to-pint ratio stays 8 to 1.
5 gallons equals 40 pints. This is a common brewing and catering benchmark because the arithmetic is just 5 times 8, so it is easy to scale quickly.
Yes, an imperial pint is 568 mL versus 473 mL for a US pint. That is about 95 mL more per glass, so the difference is noticeable when serving drinks or comparing menu prices.
A US half-barrel keg holds about 124 US pints, while a sixth-barrel holds about 41 pints. Those figures help when you are estimating servings from a keg size or planning a party.
Multiply US pints by 0.473176 or imperial pints by 0.568261. The choice of factor depends on which pint standard your source uses, so the system label matters.
