## How to Convert Fluid Ounces to Pounds

To convert a fluid ounce measurement to a pound measurement, divide the volume multiplied by the density of the ingredient or material by 15.337783.

You can use this simple formula to convert:

Thus, the volume in pounds is equal to the fluid ounces times the density of the ingredient or material divided by 15.337783.

**For example,**here's how to convert 5 fluid ounces to pounds for an ingredient with a density of 0.7 g/mL.

Fluid ounces and pounds 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.
