How ¼ cup of jam works out
One US cup of jam weighs 320 grams, so multiply by 0.25 to get a quarter cup: 320 × 0.25 = 80 g. In the other direction, 80 g of jam divided by 320 brings you back to ¼ cup.
If you have no scales, ¼ cup is 4 level tablespoons of jam (12 teaspoons), because a US cup holds 16 tablespoons. In a 250 ml metric cup — the Australian, New Zealand and modern UK standard — the same fraction is 84.5 g.
Tip: Warm jam slightly to loosen it before measuring or spreading, especially for thumbprint cookies and cake fillings where it needs to flow.
