Cups to Pints Converter
Convert US cups to pints. Enter cups and get pints, plus quarts, fluid ounces, and milliliters — all exact, since the US system defines 2 cups to the pint.
Example: with US cups 4 → Pints: 2 pints.

pints = cups ÷ 2. The chain continues: ÷ 4 for quarts, ÷ 16 for gallons — all exact US definitions.
Two cups make a pint, always
In US liquid measure the cup, pint, quart, and gallon form a doubling ladder: 2 cups to the pint, 2 pints to the quart, 4 quarts to the gallon. Halve your cup count and you have pints — 4 cups is 2 pints, 3 cups is 1.5. Because the units are defined in terms of each other, the answer is exact with no rounding.
The milliliter line uses the customary cup of 236.588 mL, so 4 cups is 946.35 mL, essentially a quart. One wrinkle worth knowing: US nutrition labels legally round the cup to 240 mL, and the old imperial system has no cup at all — its cooks measured in gills and pints. For scaling a US recipe up to pint or quart containers, the simple halving here is the whole job.
How it’s calculated
Pints = cups ÷ 2; quarts = cups ÷ 4; fluid ounces = cups × 8 (exact US definitions). Milliliters = cups × 236.588, the NIST value for the US customary cup.
US liquid measure only — the 240 mL legal cup on nutrition labels and the 250 mL metric cup used in Australia differ by up to 6 percent.

US definition: 1 pint = 2 cups = 16 fl oz exactly.
Common mistakes
- Multiplying by 2 instead of dividing — 4 cups is 2 pints, not 8.
- Scaling a UK recipe with US pints; an imperial pint holds about 2.4 US cups.
- Measuring dry ingredients in a liquid cup and expecting weight-based recipes to match — cups are volume either way.
- Confusing the produce dry pint (about 2.33 cups) with the liquid pint.
Frequently asked questions
How many pints is 4 cups?
Two pints. The formula is pints = cups ÷ 2, so 4 cups is 2 pints, which is also exactly 1 quart.
What is the cups to pints formula?
Divide cups by 2, because a US liquid pint is defined as 2 cups (16 fluid ounces). Ten cups is 5 pints; 3 cups is 1.5 pints.
Is 2 cups of sour cream the same as a pint container?
Yes by volume — pint tubs hold 16 fl oz, which is 2 cups. The weight varies by product, which is why recipes sometimes give both cups and ounces.
Do these conversions work for UK measures?
No. The imperial pint is 568.26 mL, about 2.4 US cups, and imperial recipes do not use cups at all. This tool assumes US cups and US liquid pints.
