Can a liquid UN rating be converted to a solid UN rating?
A. Yes, mathematically it can. A liquid UN rating can be converted to a solid rating using the following formula: Specific gravity (g/mL) x 3,790 mL/gal. x container capacity (gal.) x 1 lb./453.6g x 1 kg/2.21lb. = ____kg. However, if a container is not rated or designed for liquids, the container should not be used for shipping liquids.
