Cubic Centimeter (cc) or Milliliter (ml) to Ounces Unit of Capacity
To determine headspace in ounces, subtract capacity to fill point from the overflow capacity. To determine headspace in percentage, divide the capacity to fill point, into the capacity above the fill point. Example: The overflow capacity of 16oz. Boston Rounds is 17 ounces; therefore the headspace is 1oz. or 6.25% (1 divided by 16×100).
