About Fluid Ounce (fl oz)

A US customary unit of liquid volume equal to 1/128 of a US gallon (about 29.57 mL). Fluid ounces are the standard unit on US beverage containers, shampoo bottles, cooking recipes, and cocktail recipes — a standard US soda can is 12 fl oz, a large Starbucks drink is 20 fl oz, and most cocktails call for 1.5 fl oz of spirits. Easy to confuse with the Imperial fluid ounce (~28.41 mL) used in the UK, though the difference is small enough that it rarely matters for everyday use.

About Milliliter (mL)

A metric unit of volume equal to one thousandth of a liter (0.001 L) or exactly one cubic centimeter. Milliliters are the everyday metric unit for medicine dosing, cooking measurements outside the US, laboratory chemistry, perfume and beverage cans. A standard medical syringe is 10 mL; a shot glass is about 44 mL; a standard intravenous saline bag is 500 or 1,000 mL. In chemistry and pharmacy, mL and cc (cubic centimeters) are used interchangeably.
