```The short answer to your question is that the density of plain mild steel
is 7.85.

The long answer is that depending on where you look, or the grade of steel
that you are talking about can change this value.  A density of 7.88 is
often quoted for mild steel as well.  If you add alloying elements such as
tungsten, chrome or manganese to improve the steel, the density will
change.  So the long answer is that the density of steel can vary between
7.75 and 8.05.

To calculated the mass of steel, you can work on the basis that steel
weighs 0.283 lb/cu in. So...
a) 1 lb of steel is 1/0.283 = 3.5 cu in.
b) To calculate the mass of a steel plate, take the dimensions in inches
and then, width x thickness x length x 0.283 = lbs of steel.

Unfortunately, I was not able to find any internet sites that has a list of
references for densities of other materials.
