What does 100 sg densite mean?

"100 sg densite" likely refers to a specific measurement of density, where "sg" stands for specific gravity. Specific gravity is a dimensionless quantity that compares the density of a substance to the density of water. A specific gravity of 100 would imply that the substance is 100 times denser than water, which is highly unusual, as most materials have specific gravities less than 1. This could indicate a misunderstanding or miscommunication, as typical specific gravity values are usually expressed in a range from 0 to a few, not as high as 100.
