I noticed there is an EnergyDissipation field for gascell. Its unit is listed as '$(1/a)10^{10}M_\odot/ckpc(km/s)^3$', but the notes state that converting it to physical units only requires multiplying by (1/a). I'm confused because there is already a (1/a) in the unit, and converting from ckpc to pkpc also requires a (1/a) factor, so if the final converting factor is (1/a)^2?
Dear Prof.Nelson,
I noticed there is an EnergyDissipation field for gascell. Its unit is listed as '$(1/a)10^{10}M_\odot/ckpc(km/s)^3$', but the notes state that converting it to physical units only requires multiplying by (1/a).

Looking forward to your reply. Thanks!
