I have the following variables:
d (density) in gm per cm*cm*cm,
s (area) in cm*cm,
n (atoms per ml) = density*Avagadros number* Moles per gram

Units of D are gm/(cm*cm*cm)
Units of s are cm*cm
Units of n are calculated by SMATH to be gm/(m^3 kg) (ok conceptually, would like to get rid of grams per kilogram)
How do I get that to 1/(cm^3)? I've tried lots of unit operations and I'm stymied.

Similarly, I calculate t=1/(n*s), results should be in cm, but SMATH calculates (kg * cm / gm). Is there a way to get this normalized to just cm?

Thank you!

Construct the project in the SI unit system.
BTW, density is what = nothing/anything.
"weight density" has meaning, in SI kg/m³

Sure that gm is correct for gram? Used to be in very old SMath versions. Now it is g. It should be obvious from the dynamic assistant whether a given unit is available or not.

Hi. This is a picture about what Martin says:
