GitHub seems to support [citation files](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-citation-files) for repositories. This makes citation information in BibTeX and other formats. See also [this](https://guides.github.com/activities/citable-code/) and [this](https://academia.stackexchange.com/questions/14010/how-do-you-cite-a-github-repository).

There is a curious case of [absorbed dose](https://en.wikipedia.org/wiki/Absorbed_dose) vs. [equivalent dose](https://en.wikipedia.org/wiki/Equivalent_dose) vs. [effective dose](https://en.wikipedia.org/wiki/Effective_dose_(radiation)). First one is measured in [grays (Gy)](https://en.wikipedia.org/wiki/Gray_(unit)), other two in [sieverts (Sv)](https://en.wikipedia.org/wiki/Sievert), all are equivalent dimension-wise...

There are plans, but there are technical difficulties (namely the transcendental conversion ratio between radians and degrees). See #99 and #195.

> Final conversion to a real radians number could be left up to the user This will definitely become a source of errors, because people can't be trusted.

I was thinking about taking C++ logo and making "C" part into a [caliper](https://en.wikipedia.org/wiki/Calipers#Outside_caliper) or [micrometer](https://en.wikipedia.org/wiki/Micrometer_(device)) measuring the "++" part.

> Do we have an actual example of a logarithm (or other non-linear) scale of a quantity with unit? There are a few in chemistry: [pH, pOH](https://en.wikipedia.org/wiki/PH), [pKw](https://en.wikipedia.org/wiki/Self-ionization_of_water), [pKa](https://en.wikipedia.org/wiki/Acid_dissociation_constant), etc....

I am a bit confused, the issue claims to be about "Steradian based units", but we seem to discuss `luminous_flux`... I am no expert in luminous units, so I had...

> The steradian is exactly equivalent to the radian-squared. This is debatable. As per today's SI, both radian and steradian are dimensionless and therefore steradian is indeed exactly equivalent to...

> It sounds like you agree that radians squared are equivalent to steradians for infinitesimal angles. Well, computing a _macroscopic_ solid angle is equivalent to an integral over _microscopic_ solid...

> 2. Define `lumen` as the product of `candela` and `steradian`. I totally agree. This is true regardless of the definition of `steradian` (dimensionless, equivalent to radian squared or whatever)...
