Why ingredient matters
A cup is a measure of volume; a gram is a measure of mass. The same cup of flour and a cup of honey weigh wildly different amounts because their densities differ. For baking — where ratios matter — always weigh dry ingredients on a kitchen scale if you can.
Most useful conversions
- 1 cup of all-purpose flour ≈ 125 g
- 1 cup of granulated sugar ≈ 200 g
- 1 cup of butter ≈ 227 g (= 2 sticks)
- 1 fl oz (US) = 29.57 ml
- 350 °F = 175 °C (the canonical "moderate oven")
FAQ
