How Much Is 20.4 Grams of Soy Sauce in Fluid Ounces?

20.4 grams of soy sauce equals 0.64 fl oz. Soy sauce has a density of 255g per cup. Because grams measure weight and fluid ounces measure volume, the result depends on the ingredient's density.

Formula and Step-by-Step

grams ÷ 255g/cup × 8 = fluid ounces
  1. Start with 20.4 grams of soy sauce
  2. 1 cup of soy sauce = 255g
  3. 20.4g ÷ 255g/cup = 0.08 cups × 8 = 0.64 fluid ounces

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

What is a Fluid Ounce?

Fluid ounces measure how much space a liquid takes up, while ounces (oz) measure weight. 1 fluid ounce of water weighs close to 1 oz, but for other liquids like honey or oil, the weight per fluid ounce is different.

Frequently Asked Questions

About 0.64 fl oz, based on soy sauce having a density of 255g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 255 (grams per cup) to get cups, then multiply by 8 to get fluid ounces. For 20.4 grams: 20.4 ÷ 255 = 0.08 cups × 8 = 0.64 fl oz.
For the most accurate results, weigh soy sauce on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of soy sauce changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 0.64 fl oz ÷ 8 = 0.08 cups, then 0.08 × 255g/cup = 20.4g. Or use the Fluid Ounces to Grams converter.
