How ½ cup of soy sauce works out
One US cup of soy sauce weighs 255 grams, so multiply by 0.5 to get half a cup: 255 × 0.5 = 128 g. In the other direction, 128 g of soy sauce divided by 255 brings you back to ½ cup.
If you have no scales, ½ cup is 8 level tablespoons of soy sauce (24 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 135 g.
Tip: Dark soy sauce is thicker and used mainly for colour; light soy sauce does the seasoning. Don't swap one for the other by volume without tasting.
