Quarts to Cups Converter
US liquid measure is a clean ladder of fours: 1 quart = 4 cups, and 4 quarts make a gallon. Convert quarts to cups or back, with fluid ounces alongside.
Example: with Amount 1 · Direction Quarts → cups → Converted amount: 4 cups.

Every US liquid quart holds exactly 4 cups — whether it’s broth, milk, or ice cream, the measure is the same. Multiply quarts by 4 for cups: a 2-quart pitcher is 8 cups, and 4 quarts are 16 cups, which is also one gallon. Divide by 4 to go back: 6 cups of stock is 1.5 quarts, and a single cup is 0.25 quart.
The full ladder: 1 quart = 2 pints = 4 cups = 32 fl oz = 0.946 liter. That last figure matters when recipes cross borders — a liter is about 5% more than a quart (1 L = 1.057 qt), and an imperial (UK) quart is bigger still at 1.136 L. There’s also a separate US dry quart of 1.101 L used for produce baskets; kitchen liquids always use the 0.946 L liquid quart.
How it’s calculated
Cups = quarts × 4 and quarts = cups ÷ 4, exact US customary definitions (NIST Handbook 44): 1 US liquid quart = 2 pints = 4 cups = 32 fl oz = 0.946352946 L. The fluid-ounce row multiplies quarts by 32 (or cups by 8). Metric comparisons in the text use 1 L = 1.0567 US qt.

Common mistakes
- Mixing quarts with the imperial quart (40 imperial fl oz ≈ 1.136 L) in UK recipes — it’s 20% larger than the US quart.
- Confusing liquid quarts with US dry quarts (1.101 L) used for berries and produce.
- Halving badly: half of 1½ quarts is 3 cups, not 2 — convert to cups first, then divide.
Frequently asked questions
How many cups are in a quart?
Exactly 4 US cups per US liquid quart — the definition, not an approximation. Two cups make a pint, and two pints make the quart.
How many cups is 4 quarts?
4 × 4 = 16 cups, which is exactly 1 US gallon (128 fl oz).
How many quarts is a cup?
One cup is ¼ (0.25) of a quart, so 8 cups make 2 quarts.
How many fluid ounces in a quart?
32 US fluid ounces — each of the quart’s 4 cups holds 8 fl oz.
Is a quart the same as a liter?
Close but not equal: 1 US quart = 0.946 L, and 1 L = 1.057 qt. A liter of milk is about a quarter-cup more than a quart.
