Method and sourceUS cup to ml Conversion Formula
To convert US cups to millilitres, multiply the cup value by 236.588. One US customary cup equals 8 US fluid ounces or 236.588 ml. Heads up for Aussie cooks: our metric cup holds 250 ml — about 5.7% more — so a US recipe's "cup" isn't the same as the one in your kitchen drawer.
Cups and Milliliters Explained
Cups (cup)
The US customary cup is a volume of exactly 236.588 millilitres — one-half of a US liquid pint and one-sixteenth of a gallon, equal to 8 US 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 standardised, so one level cup of liquid is the same in every American kitchen.
Where it is used: The dominant kitchen measure in the United States; also appears in older recipes across Canada, Latin America and Japan (as 200-250 ml variants).
Origin: Formalised in the United States in the late 19th century from the traditional half-pint; Fannie Farmer's 1896 cookbook cemented level, standardised cups over heaped spoon measures.
Milliliters (ml)
The millilitre (ml) is one-thousandth of a litre and the natural unit for kitchen-scale liquids in the metric world. Australian measuring jugs, milk bottles, cream cartons and medicine doses are all marked in millilitres. One US cup converts to 236.588 ml — which is why it sits just under the 250 ml line of an Australian metric cup, and why the two are so easy to mix up.
Where it is used: The universal liquid measure for cooking, beverages and pharmacy across Australia and most of the world; the standard graduation on metric kitchen jugs and dosing devices.
Origin: A decimal fraction of the French Revolutionary litre; adopted in Australia with metrication in the 1970s and identical to the cubic centimetre.

When You Need Cups to Milliliters Conversions
Baking from US recipe blogs
American cake and cookie recipes pour milk and oil in cups, but your Australian jug reads millilitres. Converting as you go — 1.5 cups of milk is 354.88 ml, 0.75 cup of oil is 177.44 ml — keeps a sponge's hydration exact instead of "close enough", which is the margin between a good rise and a flat, sad flop.
Cooking rice and grains
Rice packets from Asia specify water in ml, while American guides speak in cups. Knowing 2 cups of water is 473.18 ml lets you run a 1:1.5 jasmine ratio (2 cups of rice to 710 ml of water) in the same rice cooker without reaching for a second measuring jug.
Brewing filter coffee at home
Australia's specialty coffee scene runs on grams and ratios, but US brewing guides often talk in cups. A 3-cup morning brew is 709.76 ml of water; converting cups to ml lets you dial in a 1:16 ratio on your scales without mixing conventions mid-brew — at home in Melbourne or camping along the Great Ocean Road.
Mixing pikelet and muffin batters
Weekend batters mix wet and dry in cups, but Australian buttermilk cartons state ml. When the recipe wants 2.5 cups (591.47 ml) and your carton holds 500 ml, the conversion tells you exactly how short you are — one small tub of yoghurt (about 175 ml, three-quarters of a cup) tops it up precisely.

About Our US Cups to Millilitres Converter
Our free online cups to millilitres converter gives instant, accurate liquid conversions for Australian home cooks working with American recipes. Australia went metric in the 1970s, so every Australian recipe — from a classic pavlova to a weeknight stir-fry — assumes a 250 ml metric cup and a jug graduated in millilitres. American recipes, meanwhile, count on a 236.588 ml customary cup. That 13.4 ml gap is barely a pinch in a soup, but it's enough to dry out a sponge or toughen a batch of brownies. This converter applies the exact US cup of 236.588 ml so American bakes turn out the way the recipe author intended — whether you're baking a birthday cake in Brisbane or pulling a flat white at home in Melbourne. From scaling a wedding cake to a Sunday batch of Anzac biscuits, precise cup-to-ml conversion is the difference between following a recipe and fighting it.
Expert Tips for cup to ml Conversion
Anchor numbers for bakers: 1/4 cup = 59.15 ml, 1/3 cup ≈ 78.86 ml, 1/2 cup = 118.29 ml, 1 cup = 236.59 ml and 2 cups = 473.18 ml.
Know your jug: Australian measuring cups and jugs are built around the 250 ml metric cup, so pouring a US recipe's "one cup" to the 250 ml line adds about 5.7% extra liquid — usually harmless in a soup, occasionally decisive in custard or pavlova meringue.
Scaling a recipe up or down? Convert cups to ml first, then multiply — 236.588 × 1.5 = 354.88 ml is far easier to measure than "1 1/2 cups" when your jug has no cup markings.
Coffee runs on ratios: one 236.59 ml cup of water to about 15 g of grounds makes a 1:16 brew. A 3-cup pour (709.76 ml) wants roughly 44 g of coffee — easy maths on the scales before your first flat white of the morning.
Australian and Canadian recipes already assume a 250 ml cup, so don't convert those — treat each metric cup as exactly 250 ml. The 236.588 ml figure applies only to US recipes; multiplying an Aussie recipe's cups by 236.588 starves it by 5.7%.
