How to convert quarts to cups
A US quart equals 4 cups, so cups = quarts × 4. So 2 quarts × 4 = 8 cups. A quart is also 2 pints or 32 fluid ounces.
The whole US liquid ladder is built on doubling: 1 cup = 8 fl oz, 2 cups = 1 pint, 2 pints = 1 quart, and 4 quarts = 1 gallon. That makes half a quart 2 cups, a quarter quart 1 cup, and 3 quarts 12 cups.
In metric terms a US cup is 236.6 mL and a US quart is 946.4 mL, so a quart is very close to a litre — near enough for stock or soup, but not for baking, where the 5% gap will show.
A quick pass through the cups to mL calculator saves a step later on.

How to use this calculator
Enter the number of quarts to see cups, plus pints and fluid ounces. Handy for scaling recipes and batch cooking.
Reference conversions worth keeping to hand: 0.5 qt = 2 cups, 1 qt = 4 cups, 1.5 qt = 6 cups, 2 qt = 8 cups, 4 qt = 16 cups. Multiply quarts by 32 if you want the answer straight in fluid ounces.
One warning: cups measure volume, so a cup of flour and a cup of water do not weigh the same. This conversion is exact for liquids like stock, milk and juice, but for dry ingredients it only tells you the volume — the weight depends on the ingredient. Note as well that a US legal cup used on nutrition labels is 240 mL rather than 236.6 mL, a difference small enough to ignore in cooking but worth knowing when a label and a recipe disagree.
