Calculate Coal Specific Gravity online:

The Small unility below let you calculate the Specific Gravity of Coal. It also gives you the the value for the Tons / Acre-inch value for the coal. In this program, the following assumptions are made:
MaterialAssumed Specific Gravity
Coal1.3
Boney Coal1.5
Bone1.7
Carbonaceous Shale2.2
Rock2.25

Note:
I wrote this small utility to save myself some time calculating Coal Density Calculations. Please try with a known "result" and make sure you understand the math behind such calculations. I will not be responsible for the use of this program by you. Thanks.
