How ⅓ cup of water works out
One US cup of water weighs 237 grams, so multiply by 0.333 to get a third of a cup: 237 × 0.333 = 79 g. In the other direction, 79 g of water divided by 237 brings you back to ⅓ cup.
If you have no scales, ⅓ cup is 5.333 level tablespoons of water (16 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 83.5 g.
Tip: Remember that 1ml of water = 1g, so any water measurement in millilitres is essentially the same number in grams.
