How many grams are in a cup of flour?
About 125 grams of all-purpose flour, spooned into the cup and leveled. A cup of granulated sugar is about 200 grams.
How many grams are in an ounce?
28.35 grams. For cooking, 28 grams is close enough, and a pound is about 454 grams.
Can I see a recipe in metric?
Yes. Every recipe page has a US and Metric switch next to the ingredients, along with servings that scale the amounts.
