Candela is lumen density per solid angle.
Bibliography:
1 Watt equals 683 Lumens of light power at wavelength 555 nm. At other wavelengths 1 Watt is less Lumens as it takes into account the sensitivity of the average human eye.
Candela is Lumen density per solid angle. A sphere emitting 1 Candela uniformly in all directions produces 4π Lumen total power.

Ciro Santilli 35 Updated 2025-04-05 +Created 2024-07-29A dimension in a system of units is something like length, weight or time, without considering how to assign numerical values ot them, which requires units of measurement such as the meter, kilogram or second.
Talking about dimensions can be useful when explaining new derived units without worrying about the exact units involved. See e.g. this table: en.wikipedia.org/w/index.php?title=Lumen_(unit)&oldid=1233810964#SI_photometric_units
Stack Overflow does have an super naive reputation and moderation system and overly restrictive subject matter, which Ciro Santilli wants to improve upon with OurBigBook.com.
However, it is the best that we have now, and if you use it like Ciro, you won't get tired:What else would you expect from a naive algorithm system that has 10 million newbies asking stuff?
- monitor only rare tags that you know a lot about, let others answer duplicates on big tags for you
- only answer on bigger tags when you find a better answer than can be found on the page
- accept that sometimes things are bound to go wrong, that reputation is meaningless, and move on
The key problem of Stack Overflow is closurism. The answer close feature is just not made for purpose. The sole purpose of "closing" should be to prevent easy reputation farming. What it should do instead, is remove points gained from duplicates and off topic questions. But it should not prevent new answers. The disk space costs nothing, and Google doesn't care about the closed status of a question.
As of 2024, the only competitor of Stack Overflow is Reddit (besides LLMs, which do nothing but extract data from those two and other sites). Reddit removed the mandatory thread locking after 6 months, but still lacks the Q&A focus required for greatness. Its community however is much more chill and doesn't close and downvote the fuck out of everything.
