How to convert cup to mL

A "cup" is not an internationally standard measurement: the US legal cup is 236.588 mL, the US customary cup used in older recipes is close but not identical, the metric cup used in Australia, Canada and New Zealand is a round 250 mL, and Japan's traditional rice-cooker cup is 180 mL. A recipe that just says "1 cup" with no origin given is genuinely ambiguous by up to 25%.

Because a cup measures volume rather than weight, and ingredients pack to different densities, professional and precision baking has moved toward weighing flour and sugar in grams instead. The cup-to-millilitre conversion here is exact, but it does not solve the separate, larger problem of a "cup of flour" varying by how firmly it was packed into the measuring cup.
