How Many Milliliters Is a Cup, and Is the US Cup vs Metric Cup Gap Real?
No, they are not the same: a US customary cup holds 236.6 mL, while a metric cup holds 250 mL, about 6 percent more. US nutrition labels round the cup to 240 mL, and Japan uses a smaller 200 mL cup. For most cooking the gap is too small to notice, but in baking it can add up.
