What a cup of sour cream weighs, and why it can differ

USDA’s weight for “1 cup” is 230 g. Next to a cup of water, which holds about 236.6 g, that is 97% of the weight of a cup of water, so it weighs about the same as the same volume of water. The same cup works out at 0.97 g per millilitre.

USDA lists one cup measure for sour cream (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.

USDA lists no teaspoon measure for this entry, so that weight is the cup weight divided by the US ratio (48 teaspoons to the cup).

USDA lists slightly different weights for the tablespoon and the teaspoon here: 3 teaspoons come to 14.4 g and 1 tablespoon is 12 g. The gap is rounding in the source figures.
