1. 1
   Take your value in cups

   Start with the number of cups (cup) you want to convert.
2. 2
   Multiply by 0.50721

   The conversion factor from cup to pt is 0.50721. Multiply your value by this number.
3. 3
   Read the result in pints

   The result is your value in pints (pt).

Multiply the value in cups by 0.50721. For the reverse direction, multiply by 1.971569.

• ✓US cup = 240 ml common; 236.6 ml legal; UK cup = 284 ml; metric cup (AU/NZ) = 250 ml.
• ✓Weights (grams) are more reliable than cups — a cup of flour can vary 30% depending on how packed.
• ✓For baking, always use the recipe author's country convention.

• ✗Using a UK 284 ml cup for a US recipe calling for 240 ml — 18% overshoot.
• ✗Treating all dry ingredients as 1 cup = 240 g — only true for water.
• ✗Using a coffee mug as a "cup" — mugs vary 200–400 ml.

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.

What is the Pint?

The pint equals exactly one half of a US quart (0.473176473 liters) in the United States and 0.568261 liters in the United Kingdom (the imperial pint, 20% larger than the US pint). The British pint is iconic in pub culture — beer and cider are served in imperial pints in UK pubs, and the imperial pint glass is a regulated measure required by law. In the United States, milk is commonly sold by the pint (often as half-quart cartons), and ice cream containers are often pints (16 fl oz US). The pint relates to the gallon (8 pt = 1 gal), the quart (2 pt = 1 qt), the cup (2 cups = 1 US pt), and the fluid ounce (16 fl oz = 1 US pt; 20 fl oz = 1 imperial pt). The discrepancy between US and UK pints reflects the older 1824 imperial reform that the United States did not adopt.
