Millilitres to US fluid ounces divides by 29.5735 (1 US fl oz = 29.5735 mL). A 355 mL standard soda can is 12.00 US fl oz; a 750 mL wine bottle is 25.36 US fl oz. The UK fluid ounce (28.4131 mL) is slightly smaller — a 568 mL UK pint is 20 imperial fl oz but 19.22 US fl oz. Cocktail recipes from US bartenders default to US ounces; UK and European bars use millilitres directly.
Skincare and fragrance formulators use this when a lab batch sheet is metric but the retail bottle is sold by the US fluid ounce. A 30 mL serum bottle is 1.01 fl oz; a 100 mL travel bottle is 3.38 fl oz; a 473 mL bulk refill is 16.0 fl oz. Regulatory labelling in the US requires the fl oz figure to be accurate to the stated precision, so formulators round the shelf copy to two decimals even though the underlying batch was mixed in exact millilitres.

The milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter, or one cubic centimeter. It is the everyday unit for medication dosing, beverage sizes outside the US, and cooking in most of the world. Note that a US fluid ounce is 29.5735 mL, while a UK fluid ounce is 28.4131 mL.
The US fluid ounce (fl oz) is a customary unit of volume equal to 1/128 of a US gallon, or about 29.5735 mL. It is the standard unit for liquid serving sizes on US nutrition labels. The US fluid ounce is slightly larger than the UK fluid ounce (28.4131 mL) — confusingly, the opposite direction from the gallons.
