Water
Good baseline ingredient because 1 ml water is close to 1 gram.
Flour
Light and airy, so 1 cup flour weighs much less than 1 cup liquid.
Sugar
Denser than flour. Granulated and powdered sugar have different values.

Frequently Asked Questions
Is grams to cups always the same?
No. It changes by ingredient density and by cup standard.
Which cup should I choose?
Pick the one used by your recipe source: US customary, US legal, or metric.
How many grams is 1 US cup of water?
About 236.6 grams, because a US cup is 236.588 ml and water is near 1 g/ml.
Can I enter my own ingredient density?
Yes. Select Custom in Ingredient and enter density in g/ml.
Why do flour results vary between recipes?
Flour packing, sifting, and brand differences change density and therefore cup weight.
