You can use this simple formula to convert:
Thus, the volume in ounces is equal to the fluid ounces multiplied by 1.043176 times the density of the ingredient or material.
Fluid ounces and ounces are both commonly used to measure cooking ingredients.
For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.
The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the volume to weight conversion.
