I am currently writing my master's thesis with LaTeX and most things really go super good and a lot better than in Word, but I can't seem to get this one working. What I want:
60 yE/m2s (I hope you know what I mean...)
This is what I tried so far:
\SI{60}{\micro\einstein\per\meter\squared\second}
I installed the package correctly as it's working fine with other units like:
\SI{20}{\degreeCelsius}
