Cups to pints converter: kitchen volume in US measure
One US pint equals exactly two US cups. The conversion is a clean factor of 2 in both directions: divide cups by 2 to get pints, or multiply pints by 2 to get cups. The relationship is fixed by US customary measure and does not require any rounding. The Imperial pint used in the UK is roughly 20 percent larger and follows a different cup ratio.
This calculator assumes US customary measurement, which is the standard in American cookbooks, food packaging, and recipe sites. If you are working from a British, Australian, or Canadian recipe, check whether the pint is Imperial (568 mL) or US (473 mL). The difference is enough to ruin proportions, especially in baking.
The cups to pints rule
The rule is exact: 2 US cups = 1 US pint. The factor is 2, regardless of what is in the cup. Whether you are measuring water, broth, milk, flour, or sugar, the volume relationship between cups and pints is the same. The cup-to-pint conversion is one of the cleanest ratios in the US customary system, second only to the doubling structure of teaspoons-to-tablespoons (3 tsp = 1 Tbsp).
Note that volume measure does not give you weight directly. One cup of flour weighs about 120 g, but one cup of sugar weighs about 200 g. Baking recipes increasingly list ingredients by weight (grams or ounces) for that reason, but volume measure dominates everyday American cooking and is the only way most home kitchens are equipped to measure.
What is a cup?
The US legal cup is defined as exactly 240 mL for nutrition labeling, and as 236.588 mL for traditional volume measure. The customary cup (the older 8-fluid-ounce definition) is the one used in cookbooks and on standard measuring cup sets; the 240 mL legal cup appears on food labels for serving-size disclosure. The two differ by about 1.4 percent, which is below the precision of most home measurement.
The cup as a standardized cooking unit was popularized by Fannie Merritt Farmer's "Boston Cooking-School Cookbook" (1896), which introduced level cup and spoon measurements to replace the earlier "handful" and "teacup" conventions. Before Farmer, American recipes used loose descriptive measures; afterward, the cup became the standard reference for ingredient quantity.
What is a pint?
The US pint is defined as 1/8 of a US gallon, which makes it 473.176 mL or 16 US fluid ounces. The word "pint" descends from Old French "pinte", used since at least the 13th century for a liquid measure of approximately this size, though the exact volume varied by region and commodity. The US pint settled into its modern definition in 1828, when the US Customary system formally adopted the British wine gallon as the standard.
The US pint and the UK Imperial pint are based on different gallon definitions. The US adopted the older British wine gallon (231 cubic inches, 3.785 L) in 1828. The UK redefined its gallon in 1824 to a slightly larger value (4.546 L) based on 10 pounds of water at 62°F. Both nations kept the 8-pints-per-gallon convention, so the divergence at gallon level produces the 473-mL-vs-568-mL pint we have today.
The cups to pints formula
One factor, two directions:
cups ÷ 2 = pintspints × 2 = cups1 US pint = 473.176 mL = 16 fl oz1 US cup = 236.588 mL = 8 fl ozA worked example: a soup recipe calls for 6 cups of stock. Divided by 2, that is 3 pints. The same recipe could be quoted as 3 pints, 1.5 quarts, or 0.375 gallons; the volume is identical, just expressed at different scales.
US vs Imperial pint
Two different pints coexist in English-speaking kitchens. The US pint is 473 mL; the UK Imperial pint is 568 mL. The ratio is 1 Imperial pint = 1.201 US pints, so an Imperial pint is roughly 20 percent larger. Canadian and Australian recipes follow various conventions, with newer Australian recipes using metric units and older Canadian recipes leaning toward Imperial.
The practical impact: a British recipe asking for 1 pint of milk needs 2.4 US cups, not 2 US cups. The 20 percent difference is significant in custard, ice cream, or a cream sauce, where the liquid-to-solid ratio determines texture. For draft beer the difference is just cultural lore; for baking it is a recipe killer.
Imperial pints are 20 percent larger than US pints. A recipe from a British source asking for "1 pint of cream" needs 2.4 US cups, not 2. Confirm the recipe's country of origin before measuring. When in doubt, weigh ingredients in grams instead of measuring by volume.
Cups and pints in cooking
Cup is the dominant US recipe unit for both liquids and dry goods. Pint appears in two contexts: commercial packaging (pint of cream, pint of ice cream) and large-batch cooking where the cup count becomes inconvenient. A recipe calling for 8 cups of chicken stock is usually rewritten as 4 pints or 2 quarts in commercial settings, even though all three express the same volume.
Canning recipes use pints almost exclusively. A "pint jar" is a specific glass jar size (about 473 mL, matching the US pint). Recipes for jam, pickles, salsa, and tomatoes are scaled to pint or quart jars, with the cup count of ingredients backed out from the pint yield.
For recipes that double or halve cleanly, start in cups (the more granular unit) and convert to pints or quarts only at the final scale. 6 cups halved is 3 cups; 6 cups doubled is 12 cups = 6 pints = 3 quarts. The clean factor structure of the US customary system (2× at every step from cup to gallon) makes recipe scaling almost as easy as the metric system.
Cups to pints conversion table
The most-searched values, with kitchen context.
- 1 cup = 0.5 pints (single recipe quantity)
- 2 cups = 1 pint (pint of milk, broth)
- 4 cups = 2 pints (1 quart, box of stock)
- 6 cups = 3 pints (medium-batch sauce)
- 8 cups = 4 pints (half-gallon, large batch)
- 10 cups = 5 pints (party-size punch)
- 16 cups = 8 pints = 1 gallon (canning batch)
- 32 cups = 16 pints = 2 gallons (stock pot)
Common cup-to-pint mistakes
Mixing US and Imperial pints. The difference is 20 percent. Always confirm which pint a recipe means before measuring.
Confusing volume with weight. A cup of flour and a cup of sugar are the same volume but different weights. For baking precision, weigh in grams.
Forgetting that the cup factor is 2. Some cooks divide by 4 by reflex (because there are 4 quarts in a gallon). The cup-to-pint factor is 2, not 4.
Treating a coffee mug as a measuring cup. A standard coffee mug holds about 1.25 to 1.5 cups (300-355 mL), not 1 cup. Use a graduated measuring cup for recipes, not whatever mug is in the cupboard.
