Its dye and fluid ounces. No sure why it is done this way but its an
entrenched habbit now and no one wants to change. They just want a chart so
they do not have to spend the time to calclate. Since 30 cc = 1 fluid ounce,
when the measurement gets to 30 cc I want to show 1 oz. When measurement is
33 cc I want to show 1 oz 3 cc. Crazy huh! I so appreciate any help Pete.

But cubic centimeters are a measure of volume and ounce is a measure of
weight. The conversion will depend on the density of the liquid you are
using - is this water?
