[yt-users] Custom units.

[Kuo-Chuan Pan]

Dear all,

I have a custom new derived field based on density (g/cm^3) and entropy (kB/baryon but it is recognised as dimensionless). 
Currently, this new derived field is set to dimensionless (it should be kB/baryon).

Could anyone teach me how to set this new derived filed to its correct unit (which should be kB/baryon)?
Or is it possible to simply override the field label in my volume rendering plot before using save_annotated()?

Many thanks,
