How to Convert Fluid Ounces to Kilograms
To convert a fluid ounce measurement to a kilogram measurement, divide the volume multiplied by the density of the ingredient or material by 33.814023.
You can use this simple formula to convert:
Thus, the volume in kilograms is equal to the fluid ounces times the density of the ingredient or material divided by 33.814023.
Fluid ounces and kilograms 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. 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.

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as an "ounce" but should not be confused with the unit of mass. One fluid ounce is equal to just under 29.6 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.
The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as fl. oz. or oz. fl.. For example, 1 fluid ounce can be written as 1 fl oz, 1 fl. oz., or 1 oz. fl..
The definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.
The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
