A recipe calls for 3/4 cup sour cream — how many grams is that?

3/4 cup × 240 g = 180 g. Sour cream's smooth texture means a level cup measurement is reliably close to its weight.

Can I substitute Greek yogurt for sour cream using the same weight?

Yes — Greek yogurt and sour cream have similar densities (both around 235-245 g per cup), so a gram-for-gram substitution works well, though Greek yogurt is slightly tangier and less rich.

Sour Cream: 240 Grams

Sour cream weighs about 240 g per cup, very close to milk and yogurt since all three are dairy products with similar water content. It measures consistently by volume since its smooth, uniform texture doesn't trap air pockets the way drier ingredients can.
