Formulas
cups = quarts × 4 (US liquid)
cups = quarts × 4.6546 (US dry, approximate)
cups = quarts × 4 (Imperial, but cup is 284.131 mL)
Why the numbers change
Most “how many cups in a quart” blog posts assume US liquid. But bulk ingredients (like berries or flour) may be listed in US dry quart, which is a little larger, so you get more cups from the same “quart.” UK/imperial recipes also use larger quart and larger cups.
FAQ
1. How many cups in 1.5 quarts?
US liquid: 1.5 × 4 = 6 cups.
2. How many cups in 2 quarts?
US liquid: 2 × 4 = 8 cups. That’s half a gallon.
3. I only have metric jugs — what now?
1 US quart ≈ 946 mL, 1 US cup ≈ 237 mL, so 1 quart = 4 cups also equals about 946 mL = 4 × 237 mL.
