while dynamic analysis in abaqus or Any FEM ,the thing i faced problem is density of material.

for example for steel density is 7800 Kg/M3 .

as per abaqus documentation the density should be Tonn/MM3

But some of my friends told like for dynamic aalysis the density should be Mass density

can you brief me the reson or basic behind the units

this may be silly question any way i want to clarify this doubt..
