Then you also found that 1 cubic micron = 1x10^ -18 metersI thought I found how many cubic microns were in 1 cubic meter. Why aren't those the units that i'm using?

If you use it in microns wouldn't

m = (2500kg/m

^{3})*1x10

^{18}microns

^{3}

be in units of kg*micron

^{3}/m

^{3}

On the other hand:

m = (2500kg/m

^{3})*1x10

^{-18}m

^{3}

the m

^{3}cancels out in numerator and denominator leaving kg behind.
