Here is a rare moment of agreement: both the American and British gallon contain exactly 8 pints. The pints are different sizes, so the gallons still differ — but the count is the same, which makes the pint a handy bridge between the systems.
Quick Answer: 1 gallon equals 8 pints — in both the US and UK systems (though the pints themselves differ in size).
US: 8 Pints of 16 Ounces
The US liquid pint is 16 fluid ounces (473 mL). Eight of them make the 128-ounce US gallon. Two cups make a pint, so the chain runs: 1 gallon = 8 pints = 16 cups.
UK: 8 Pints of 20 Ounces
The imperial pint is 20 imperial fluid ounces (568 mL) — the famous British pub pint. Eight of those make the 160-ounce imperial gallon. This is why a British pint glass feels generous to American visitors.
The Pub Pint’s Story
The pint has been a regulated measure in England since the 1500s, with the crown stamping approved pint pots. The 1698 London pint and later imperial standard kept the pint central to daily commerce — milk, beer, and cream were all sold by the pint for centuries. Modern US pint and gallon definitions are maintained by NIST under the customary system.
Pint Conversions
US: 1 pint = 2 cups = 16 fl oz = 473 mL. UK: 1 pint = 20 imp fl oz = 568 mL. Half a gallon is 4 pints; a quarter gallon (1 quart) is 2 pints.
The Pint Around the World
Eight pints per gallon holds on both sides of the Atlantic, but the pint itself changes size at the border. An American pint is 16 US fluid ounces, exactly 473 mL. A British pint is 20 imperial fluid ounces, about 568 mL — a full 20 percent more beer in the glass.
British law even requires the pint measure for draught beer, which is why a “pint” in a London pub feels generous to American visitors. Ice cream plays looser: the US pint tub is a regulated 473 mL, while many brands quietly sell 14-ounce tubs that look identical. Count pints per gallon anywhere, but check the pint before you pour.
Farmers counted in pints long before supermarkets did. A pint of strawberries, a pint of cherry tomatoes — the small basket at the market stall is a dry pint, which is actually a little larger than the liquid pint at 550 mL versus 473 mL. The difference rarely matters for berries, but it completes the picture: even within one country, the pint has a liquid life and a dry life, and both still multiply eight to the gallon in their own system.

Conclusion
Eight pints to the gallon on both sides of the Atlantic — same count, different pints, zero confusion from now on. The American pint pours 473 mL, the British a protected 568 mL, and knowing which glass you hold explains a century of pub arguments and recipe mismatches.
The ladder around the pint stays friendly everywhere: 2 pints make a quart, 4 quarts a gallon, and ice cream, berries, and beer all climb it daily. Count by pints when the batch is small, convert to gallons when it grows, and check the pint’s nationality before you pour. That single habit settles every pint question you will ever meet.
