This post was last edited by lx5599 at 2009-12-18 16:51.: mass flow unit: What is Mgm/hr (milligrams per hour)? , What is Ggm/hr? Because it is a trace substance in petroleum, smaller units mg and μg are needed. How are they expressed in Aspen? It would be great if someone could convert the various units of various physical quantities in Aspen into common ones for everyone!

ASPEN PLUS has the ability to set the units yourself. SETUP----Units-sets, then click NEW to create a new unit set.

2# zhangjx73 Brother, I know about the self-built unit set you mentioned, but building it is just a recombination based on the existing ones in Aspen. Is there any difference in μg that I want to know?

Mgm/hr is 10e6 g/h=1000kg/h Ggm/hr is 10e9 g/h=1000000kg/h. Convert the smaller unit and enter it in scientific notation.
