cup to ml Conversion Formula
To convert US cups to milliliters, multiply the cup value by 236.588. One US customary cup equals 8 fluid ounces or 236.588 ml. Note: the metric cup used in Australia and Canada is 250 ml, about 5.7% larger.
Cups and Milliliters Explained
Cups (cup)
The US customary cup is a volume of exactly 236.588 milliliters — one-half of a US liquid pint and one-sixteenth of a gallon, equal to 8 fluid ounces. It is the default liquid measure of American home cooking: milk, water, oil, and broth in US recipes are nearly always counted in cups, halves, and thirds rather than weighed. Cup measures are standardized, so one level cup of liquid is the same in every American kitchen, from a Houston galley kitchen to a San Francisco Victorian.
Where it is used: Dominant kitchen measure in the United States; also appears in older recipes across Canada, Latin America, and Japan (as 200-250 ml variants).
Origin: Formalized in the United States in the late 19th century from the traditional half-pint; Fannie Farmer's 1896 cookbook cemented level, standardized cups over heaped spoon measures.
Milliliters (ml)
The milliliter (ml) is one-thousandth of a liter and the natural unit for kitchen-scale liquids in the metric world. The 2-liter soda bottle and the 16.9 oz water bottle in every American fridge are both marked in milliliters, as are measuring jugs, cream cartons, and medicine doses. One US cup converts to 236.588 ml, which is why the 240 ml line on a metric measuring cup is the stand-in for "one cup" in millions of mixed-unit kitchens.
Where it is used: Standard liquid measure on US nutrition labels, medicine dosing cups, and imported goods; the standard graduation on metric kitchen measuring cups worldwide.
Origin: A decimal fraction of the French Revolutionary liter; adopted worldwide with the metric system and identical to the cubic centimeter.

When You Need Cups to Milliliters Conversions
Baking from American food blogs
US cake and cookie recipes pour milk and oil in cups, but imported chocolate and European-style butter packaging speak metric. Converting as you go — 1.5 cups of milk is 354.88 ml, 0.75 cup of oil is 177.44 ml — keeps a red velvet layer cake's hydration exact instead of "close enough", which is the margin between a tall crumb and a flop.
Cooking rice and grains
Bags of jasmine or sushi rice often list water in milliliters, while American guides speak cups. Knowing 2 cups of water is 473.18 ml lets you run a 1:1.5 ratio (2 cups rice to 710 ml water) in the same rice cooker or Instant Pot without grabbing a second measuring tool.
Brewing pour-over coffee
Specialty coffee recipes pair grams of beans with water by cup or ml depending on the roaster's country. A 3-cup morning brew is 709.76 ml of water; converting cups to ml lets you hold a 1:16 ratio on your gram scale without switching conventions mid-brew — whether it's a Chemex in Portland or a V60 in Chicago.
Mixing pancake and muffin batters
Weekend batters mix wet and dry in cups, but buttermilk and yogurt cartons state milliliters. When the recipe wants 2.5 cups (591.47 ml) and the carton holds 500 ml, the conversion shows exactly how short you are — one single-serve yogurt cup (about 177.44 ml, three-quarters of a cup) tops it off precisely.

Scaling a recipe up or down? Convert cups to ml first, then multiply — 236.588 × 1.5 = 354.88 ml is easier than eyeballing "1 1/2 cups" on a jug with no cup markings.
Coffee runs on ratios: one 236.59 ml cup of water to about 15 g of grounds is a 1:16 brew. A 3-cup morning pour (709.76 ml) calls for roughly 44 g of beans on your scale.
