  • 1 UK quart = 2 UK pints = 1137 ml.
  • Quarts appear more often in the US than UK in everyday usage.

About Quart and Cup

What is the Quart?

The US quart equals exactly one quarter of a US gallon (0.946352946 liters) and is a common kitchen and motor-oil volume in the United States. The word 'quart' derives from the Latin 'quartus' meaning fourth. Milk and motor oil are commonly sold in quart containers (a quart of motor oil is 32 fl oz), and large recipes call for quart-sized stockpots. The US quart is distinct from the slightly larger UK imperial quart (1.137 L). It relates to the gallon (4 qt = 1 gal), the pint (2 pt = 1 qt), the cup (4 cups = 1 qt), the fluid ounce (32 fl oz = 1 qt), and the liter (1 US qt ≈ 0.946 L). The quart is a useful intermediate volume between the cup (small recipe measurements) and the gallon (bulk liquids).

  • US cooking recipe quantities
  • US motor-oil container sizes (1 quart bottles)
  • Canning and preserving containers
Real-world examples

A US quart of motor oil is 946 ml. A "quart of milk" in the US ≈ 1 L. UK "quart" is rare today.

What is the Cup?

The US cup equals exactly 240 milliliters (a definition standardized for nutrition labeling; the legal volume for cooking is 236.588 mL, derived from 8 US fluid ounces). The cup is the cornerstone of American baking and home cooking, with virtually every US recipe using volume measurements rather than the weight measurements common in European cooking. Standard measuring-cup sets include 1, ½, ⅓, and ¼ cup sizes. The metric cup (used in Australia, New Zealand, and increasingly in international recipes) is exactly 250 mL — slightly larger than the US cup. The cup relates to the gallon (16 cups = 1 gal), the pint (2 cups = 1 pt), the fluid ounce (8 fl oz = 1 cup), the tablespoon (16 tbsp = 1 cup), and the milliliter (1 cup ≈ 237–240 mL). American baking-by-volume is sometimes criticized internationally for its variability compared to gram-based measurements.

  • US cooking and baking recipes
  • Cereal and beverage serving sizes in US nutrition labels
  • Volume estimation when no scale is available
Real-world examples

1 cup of water = 240 g = 240 ml. 1 cup of all-purpose flour weighs about 125 g. A Starbucks Tall is 12 fl oz = 1.5 cups.
