Milliliters to Us Cups
A milliliter is one thousandth of a liter, equal to one cubic centimeter, used for medicine doses and small liquid measures. A US cup is 8 fluid ounces, about 237 milliliters, the standard American recipe measure for liquids and dry ingredients. 1 mL equals ≈0.00422675 cup, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to volume, measured here against volume's base unit (L) — every other volume unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
