Cups to grams, per ingredient
There is no single answer to "how many grams in a cup": a cup of flour is 120 g and a cup of honey is 340 g. Pick the ingredient, type the amount, and get the weight your scale should read, in grams and ounces.
120 g
4.2 oz
of all-purpose flour
Spooned into the cup and levelled off. Scooping straight from the bag packs it down and can give you 145 g or more, a fifth more flour than the recipe asked for.
One US cup, weighed
all-purpose flour 120 g, granulated sugar 200 g, butter 227 g, honey 340 g. Same cup, very different weights. Open an ingredient for its full table and for how the cup was filled to get that number.

Questions
How many grams are in a cup?
It depends entirely on the ingredient, because a cup measures volume and a gram measures weight. One US cup holds 120 g of all-purpose flour, 200 g of granulated sugar, 227 g of butter and 340 g of honey. Pick your ingredient above to get the right number.
Which cup does this use?
The US customary cup, 236.6 ml, which is the one American recipes mean. A UK or Australian metric cup is 250 ml, about 6% larger, and a Japanese cup is 200 ml. If your recipe is metric, type the millilitres in directly.
Why is my cup of flour heavier than 120 g?
Because of how you filled it. Scooping straight from the bag compacts the flour and can give you 145 g or more; the standard 120 g assumes you spooned it in and levelled it off. That 20% swing is the reason bakers weigh instead of scooping, and it is why halved and doubled recipes go wrong so often.
Are these conversions exact?
They are the standard US baking-reference values, and each ingredient page says how the cup was filled to get its number. For liquids and sugars they are good to within a gram or two. For anything fluffy or packable, like flour, brown sugar or grated cheese, measuring by volume carries more error than the conversion does.
