Abaqus and Units

Hi all... Wishing you all a very fantastic day... Hope your research is going well...

I want to draw box at micron or nano levels. For example, square box of side 20 microns (10^-6 meters), what should I do to the units of pressure which is in Pascals (900 Pa). Also, the shear modulus G is 400 Pascals. What to do. Some say normalise... then do I have to normalise the daimeter also? Hahaha very confusing as am going down to meters , centis, micro and nano... Help...:cool:
