This example problem demonstrates how to convert fluid ounces to milliliters.
A soda can contains 12 fluid ounces of soda. What is this volume in millilters?
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 tbe 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.
