In Dimensional analysis if L=Lenght why is L/L=1 (a dimensionless number), and not just nothing more than L/L ?
It started with that I was thinking of why degrees do not have any dimension, and then I thought of the definition of radians:
q = "angle"
s = "a length on the circles circumference"
r = "radius"
then:
s/r=q
But now we have the dimensions L/L in the equation s/r=q which then must be dimensionles if degrees is dimensionles. So to solve this problem I need to solve that.
It may have been a stupid question but I want to know, so I appreciate any help.
