Italiano1 cup = 236.59 ml: formula and example
To convert cups to ml, multiply by 236.5882365, the legal US cup: ml = cups × 236.588. Example: a biscuit recipe calls for 1 1/4 cups of buttermilk, so 1.25 × 236.588 = 295.74 ml. On a metric measuring jug, pour to just under the 300 ml line.
The converter on this page is already set to "US cup (cup)" to "milliliter (ml)". The answer updates as you type, to six significant figures (1.25 cup = 295.735 ml), and the "Formula:" line reads 1 cup = 236.5882365 ml. Type fractions as decimals: 0.25, 0.5 or 0.75. The ⇄ "Swap units" button turns ml back into cups, and the "In every unit" table gives the same amount in fluid ounces, tablespoons, teaspoons and liters.

What to know before you measure
Not every cup is the same cup
The converter uses the legal US cup, 236.59 ml. Australian, New Zealand and Canadian recipes often use a metric cup of 250 ml, 5.67% bigger, and US nutrition labels round a cup to 240 ml. Neither of those two is in the lists: for an Australian recipe, just count 250 ml per cup.
Liquids convert, flour and sugar do not
A volume conversion works for water, milk, oil, stock or cream. For flour, sugar or butter you want grams, and the weight of a cup depends on the ingredient: the site has a cooking converter for cups to grams that handles that.
Tablespoons and teaspoons
The lists offer "tablespoon (15 ml)" and "teaspoon (5 ml)", rounded values. So the converter shows 1 cup = 15.7725 tbsp, while a US cup is exactly 16 US tablespoons of 14.79 ml each. In a recipe, the gap is too small to taste.
