Fluid ounces and milliliters, side by side
One fluid ounce is 29.57 ml. In the other direction, one milliliter is 0.03381 fl oz.
The factor is exact rather than rounded: imperial and US units have been defined from the metric ones since 1959, so the conversion introduces no error of its own. What you see below is arithmetic, not an approximation.
The US fluid ounce is one 128th of a US gallon, about 29.57 milliliters, and a standard American can holds 12 fl oz. The British imperial fluid ounce is slightly smaller, about 28.41 ml, and neither has anything to do with the ounce of weight.
The milliliter is one thousandth of a liter, exactly the volume of a cubic centimeter. Medicine, cans and cosmetics are labeled in it: a standard can holds 355 ml in the United States and 330 ml in Europe, and a teaspoon is about 5 ml.
