Frequently Asked Questions
How many mL is 1 cup?
One US cup equals 236.6 mL. Many American products round this to 240 mL for convenience.
How many mL is half a cup?
Half a US cup equals 118 mL. This is often rounded to 120 mL in recipes.
Is a metric cup the same as a US cup?
No. A US cup is 236.6 mL, while a metric cup (used in Australia and some other countries) is exactly 250 mL. The difference can affect baking results.
Should I use 236 mL or 240 mL for 1 cup?
The precise value is 236.6 mL. However, 240 mL is commonly used in recipes for simpler math. For most cooking, either works. For precise baking, stick with 237 mL.
How do I measure a cup without a measuring cup?
If you have metric measuring tools: 240 mL ≈ 1 cup. You can also use 16 tablespoons = 1 cup, or 8 fluid ounces = 1 cup.
Why do bakers prefer grams over cups?
Cups measure volume, but ingredients like flour can vary in density based on how they're scooped. Weight measurements (grams) are consistent regardless of how ingredients are packed, leading to more reliable results.
