How does this calculator work?
Divide cups by 4 to get US quarts. One US quart equals 4 cups, 2 pints, 32 fl oz, ¼ gallon, and about 946.4 mL. The ratio is exact by definition. The UK Imperial quart (≈ 1136 mL) is about 20 % larger than the US quart.
Formula
How this is calculated
In US customary measure, 1 quart equals exactly 4 cups — or 2 pints, 32 fluid ounces. The conversion divides by 4: quarts = cups ÷ 4. The US volume system is built on powers of two, so each tier is double the previous: 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon. This means 1 quart is exactly ¼ of a gallon, and 1 gallon contains 16 cups.
The metric equivalent uses the exact US cup definition of 236.588 mL, giving 1 quart ≈ 946.353 mL (just under 1 litre). The US quart and the Imperial quart are close in size but not identical: 1 US quart ≈ 946 mL, while 1 Imperial quart ≈ 1136 mL — about 20 % larger.
The visualisation bar shows how the cups you entered fill complete quarts, with any remaining cups displayed as a separate segment. For example, 5 cups fills 1 complete quart (4 cups) with 1 cup left over.
