What is a US Cup? History, origin and usage

The standardised cooking cup was popularised in the United States by Fannie Farmer, whose 1896 Boston Cooking-School Cook Book championed level, measured quantities instead of vague handfuls. The US customary cup was set at half a US pint, or eight US fluid ounces.

The cup is the backbone of American and Canadian home recipes, used for flour, sugar, liquids and almost everything else, with measuring cups a kitchen staple. Most of the rest of the world weighs dry ingredients instead, finding volume cups less precise for things like flour.

There are several competing cups: the US customary cup of about 237 millilitres, the US legal cup of 240 millilitres used on nutrition labels, and the metric cup of 250 millilitres common in Australia and the UK. This is why carefully following a recipe from another country can still go slightly wrong.

What is a Millilitre? History, origin and usage

The millilitre is the litre scaled by the metric prefix milli- (Latin mille, a thousandth), so it inherits the litre's origin in the 1795 French metric reforms. Because the litre was defined in relation to the metre, the millilitre became exactly one cubic centimetre when the litre was tied to the cubic decimetre. It has been part of the coherent metric vocabulary ever since the SI prefixes were standardised.

The millilitre is the workhorse small-volume unit almost everywhere outside the United States: medicine doses, syringes and IV bags, drink and food nutrition labels, perfume and cosmetics, and home cooking. Laboratories and pharmacies use it constantly for measuring liquids. In medicine the equivalent term cubic centimetre (cc) is still heard, especially for syringes.

One millilitre is identical in volume to one cubic centimetre, because a litre is exactly one cubic decimetre. A standard metric teaspoon is taken as five millilitres, which is why liquid-medicine dosing cups are graduated in millilitres rather than spoons.

How to use this US Cup to Millilitre converter

Type a number into the US Cup field and the equivalent in Millilitre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Millilitre field to convert the other way (millilitre to us cup). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.

Accuracy and method

Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 US cup = 236.5882mL), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for us cup-to-millilitre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.

Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
