What Is a Cups to ML?
There are three different cups in everyday use. The US legal cup is 240 ml; the US customary cup (the one used in recipes) is 236.588 ml; the metric cup used in Australia, New Zealand and parts of Canada is exactly 250 ml. This tool defaults to the US customary cup because US recipes dominate the online corpus.
Bakers in metric kitchens following a US blog need this almost daily — flour, sugar, milk and oil all show up in cups. The conversion is exact in the volume direction; when you need weight, switch to the cooking-converter so ingredient density can be applied (a US cup of flour is roughly 125 g, not 236 g).
For the metric cup, multiply ml by 1/250 instead of 1/236.588 — the difference is small but adds up across a full recipe.
