ABS Material showing weird unit measure

[jls270999]

Im on Inventor 2020 trying to create a replica of the ABS Plastic to make my own version with my needed Tensile Strenght and Yield Strenght.

I need to change the density too but its not showing in g/mm3 or whatever is the normal, I have made sure its set to Metric  mmNs as i need but its showing  N-s2/mm^4 (i will upload a picture.)

Any help is appreciated!

Some how system use N (force) instead of g (mass)?

Hi! I believe N is a composite unit (kg*m/sec^2). So N*sec^2/mm^4 = 10E6g/mm^3, which is a density unit.

Many thanks!
