US Cups vs UK Cups vs Metric Cups
Not all cups are equal — this is the most common source of confusion when following international recipes:
US customary cup = 236.59 ml (used in the USA and most online recipes)
UK imperial cup = 284.13 ml (older measurement, rarely used in modern UK recipes)
Metric cup = 250 ml (used in Australia, Canada and New Zealand)
This calculator uses the US customary cup as it’s the most widely used standard in recipes worldwide. If you’re following an Australian or New Zealand recipe, your cup is 250 ml rather than 236.59 ml.
