Fluid Ounces To Milliliters Example Problem

A soda can contains 12 fluid ounces of soda. What is this volume in milliliters?


First, start out with the conversion formula between fluid ounces and milliliters:

1 fl oz. = 29.57 ml

Set up the conversion so the desired unit will be cancelled out. In this case, we want ml to be the remaining unit.

volume in ml = (volume in fl oz) x (29.57 ml/1 fl oz.)

volume in ml = (12 x 29.57) ml

volume in ml = 354.84 ml


A 12 fl oz soda can contains 354.82 ml.
