  4. Convert grams to ounces: 255 ÷ 28.3495 = 8.99 oz

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.

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

Frequently Asked Questions

About 8.99 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.
Multiply the number of fluid ounces by 31.88 (grams per fluid ounce for soy sauce), then divide by 28.3495 to convert grams to ounces. For 8 fluid ounces: 8 × 31.88 = 255g, then 255 ÷ 28.3495 = 8.99 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.
