FAQ
Frequently Asked Questions
1Why do different ingredients weigh different amounts per cup?
Because cups measure volume, not mass. Dense ingredients like sugar pack tightly, while airy ingredients like flour pack loosely. This is why volume measurements are unreliable in baking.
2How many grams is one cup of all-purpose flour?
One US cup of sifted all-purpose flour weighs approximately 125 grams. Packed flour can weigh up to 150g, which is why sifting (or spooning flour into the cup) matters in baking.
3What is the difference between a US cup and a UK cup?
A US cup is 236.6 mL, while a UK metric cup is 250 mL. When following international recipes, always check which cup measurement system the recipe uses.
4How do I convert grams back to cups?
Divide the gram amount by the grams-per-cup for that ingredient. For example, 250g of flour ÷ 125g per cup = 2 cups. Use the converter above for instant results.
