Flour Cups to Grams Converter
This converter handles flour, sugar, butter, and milk, converting your amount to grams instantly. For flour specifically, measuring technique changes the result more than which authority you follow, so the method field matters more than it looks.
Common amounts
How this is calculated
Result = amount (cups) × density (grams per cup) for the chosen ingredient and method. For flour specifically, the method field genuinely matters: spooning flour into the cup and leveling it keeps air in the flour, while scooping straight from the bag compacts it, adding 15-25% more weight to the same cup. Sugar, butter, and milk don't have this distinction, so the method field hides itself for those.
Worked example
3/4 cup of bread flour, spooned and leveled: 0.75 × 127g = 95g. The same 3/4 cup scooped straight from the bag would weigh 0.75 × 152g = 114g, a 19g difference from one measuring choice alone.
Frequently asked questions
Why does King Arthur say 120g but other sites say 125g for a cup of flour?
What's the difference between spooning and scooping flour?
How many grams in a cup of sugar, butter, or milk?
How this is checked. All-purpose flour's 120g spooned figure matches King Arthur Baking's own published standard. Pastry flour's figure was corrected during fact-checking: an earlier single-sourced value of 120g didn't hold up against King Arthur Baking's own Ingredient Weight Chart and three other independent sources, which converge on 106g instead. Bread and cake flour figures are the middle of a genuine range across multiple sources, not a single source's number presented as the only answer.
