How ¼ cup of onion powder works out
One US cup of onion powder weighs 120 grams, so multiply by 0.25 to get a quarter cup: 120 × 0.25 = 30 g. In the other direction, 30 g of onion powder divided by 120 brings you back to ¼ cup.
If you have no scales, ¼ cup is 4 level tablespoons of onion powder (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 31.7 g.
Tip: Onion powder dissolves and distributes evenly, making it ideal for dry rubs and dressings where chopped onion would be intrusive.
