None of the monitored components undergo unit conversions  (i.e. conversion factor of 1).

AUC is area under the plasma concentration curve in uM*days units with Rblood2plasma = 0.654.
The model outputs are provided in the following units:
	umol: Avehicle, Aplasma, Ain, Aexhaled, Atubules, Ametabolized
	uM: Cgut, Cliver, Cven, Clung, Cart, Crest, Ckidney, Cplasma, Cskin_exposed, Cskin_unexposed, Cvehicle
	uM*days: AUC
