How Many Pints Are in a Gallon?

There are 8 pints in a gallon in both the US and imperial systems.

Here's the full breakdown:

• 1 gallon = 8 pints
• 1 gallon = 4 quarts (so 2 pints = 1 quart)
• 1 gallon = 16 cups (so 1 pint = 2 cups, in the US)

The number of pints (8) is the same in both systems, but the actual volume differs because the gallons and pints themselves are different sizes:

• US gallon ≈ 3.785 liters, so 1 US pint ≈ 473 ml
• Imperial gallon ≈ 4.546 liters, so 1 UK pint ≈ 568 ml

So a UK pint is noticeably larger than a US pint, even though both give you 8 pints per gallon.
