Soy sauce, Cups to Grams & Grams to Cups
1 cup of soy sauce = 255 grams · 100g = 0.39 cups
Soy sauce is a salty fermented liquid that weighs about 255 grams per cup, a little heavier than water because of its dissolved salt and solids. It is rarely used by the cup — most recipes call for tablespoons — but the conversion helps when scaling up marinades and braises. Light (regular) and dark soy sauce differ in colour and saltiness.

How to measure soy sauce accurately
For the most reliable baking results, weigh soy sauce on a kitchen scale rather than scooping by volume. One US cup of soy sauce weighs about 255 grams (8.99 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts soy sauce and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
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.
