Cups to Grams Depends on the Ingredient
Volume-to-weight conversion isn't a single number - it depends on what you're measuring. 1 cup of flour weighs about 125 g; 1 cup of sugar weighs 200 g; 1 cup of butter is 227 g; 1 cup of honey is 340 g. Same volume, very different weights because each ingredient has different density.
For accurate baking, weight is far more reliable than volume. American recipes use cups by tradition; professional bakers and modern recipe writers globally are shifting to grams. When converting an American recipe, look up each ingredient's specific cup-to-gram conversion.

Frequently Asked Questions
Why is volume measurement unreliable?
Packing density varies. A 'cup of flour' can weigh 110-150 g depending on whether it was scooped (denser) or sifted (lighter). Weight measurement gives consistent results. Recipe writers who trust weight will get consistent baking; volume measurement leads to high recipe failure rates.
What's the standard cup size?
US cup = 240 ml. UK metric cup = 250 ml. The 4% difference rarely matters for cooking but can matter for baking. Use the cup-to-gram conversion that matches the recipe's origin (US recipes use US cups).
