At some point I was looking at using a units library, but came up short because I could not find one that could convert using log scale units (which I needed).

At some point I was looking at using a units library, but came up short because I could not find one that could convert using log scale units (which I needed). The same is True for gnu units. It can convert from linear to log units, e.g.: You have: 10W You want: dBm 40 but not the other way around (unless I'm missing something): You have: 40 dBm ^ Parse error I understand that log units are tricky to get right, but in some fields they are pretty ubiquitous.
