How many milliliters are in an ounce?
Here is a quick conversion chart: 100 ml = 3.3 or 3.4 oz 50 ml = 1.7 oz 30 ml = 1 oz 15 ml = 1/2 oz 10 ml = 1/3 oz 7.5 ml = 1/4 oz 5 ml = 1/6 oz 3.7 ml = 1/8 oz = 1 dram Note that all of these are approximate; strictly speaking, 1/2 oz is 14.787 ml. A standard perfume sample is in a 1/32 oz (1 ml) vial. You can see a picture showing sizes of standard perfume bottles in the article on decanting (scroll down).
