About converting Fluid Ounces (US) to Milliliters
Fluid Ounces (US) (fl oz) and Milliliters (mL) are both units of volume, so converting between them is a single multiplication: multiply your Fluid Ounces (US) figure by 29.5735. Ten Fluid Ounces (US) comes to 295.7353 Milliliters, and a hundred works out at 2,957.35 Milliliters.
Rule of thumb: going from Fluid Ounces (US) to Milliliters multiplies, so the figure always grows — one Fluid Ounce (US) is already 29.5735 Milliliters. If your answer came out smaller, you have the conversion the wrong way round.
What is a Fluid Ounce (US)?
A fluid ounce measures volume, not weight, despite sharing a name with the ounce on a kitchen scale — the two are related only loosely, through the weight of water. The US and imperial fluid ounces are different sizes, and counterintuitively the imperial one is the smaller, even though the imperial gallon is the bigger of the two: the imperial gallon divides into 160 fluid ounces, the US gallon into just 128. The gap is small enough to slip past a reader and large enough to matter, which makes it a reliable trap in cocktail recipes and drink can sizes.
What is a Milliliter?
A milliliter is one thousandth of a liter, and it is exactly the same size as a cubic centimetre — the "cc" stamped on engines and syringes measures precisely the same thing. That equivalence is quietly useful: a 600 cc motorcycle engine and a 600 mL bottle of water occupy identical volumes, so figures from medicine and mechanics can be compared without any translation at all. The milliliter dominates wherever small quantities must be stated unambiguously: pharmacy, laboratory work, cosmetics and airline carry-on liquid limits are all written in mL rather than in spoons or ounces.
To put both in perspective: a US shot of spirits is about one and a half fluid ounces, while a standard wine pour is about 150 milliliters.
