Frequently Asked Questions
How many milliliters are in a cup?
One US cup equals 236.588 mL (commonly rounded to 237 mL). Note that the metric cup used in Australia is 250 mL, and the Imperial cup (UK) is 284 mL.
Why are cup sizes different in different countries?
The US cup (236.6 mL) originated from the US customary system. Australia adopted the metric cup (250 mL) for simplicity. The UK Imperial cup (284 mL) is based on the Imperial pint (568 mL ÷ 2). Japanese recipes use a 200 mL cup. Always check which cup standard a recipe uses.
How do I measure 1 cup without a measuring cup?
One US cup is approximately 16 tablespoons, 48 teaspoons, or 8 fluid ounces. In a pinch, a standard coffee mug holds roughly 250 mL (slightly more than 1 US cup).
Should I measure flour by cups or by weight?
By weight (grams) whenever possible. A cup of flour can weigh 120-150g depending on how it's scooped, packed, or sifted — that's a 25% variance. Professional bakers always measure by weight for consistency.
