To add to that:
specific gravity is based on water wich has a specific gravity of
1.0000 grams per milliliter or 1.0 gr/ml;
or
1.0000 grams per cubic centimeter or 1.0 gr/cc
if materials are lighter then the number is lower than 1.0
(corn oil has a specific gravity of 0.922 gr/cc)
and
heaveir items (such as what you have would be grater than 1. 0
The rest is strictly a matter of converting your metric units to get the units you wish to work with.
