Arcsin transform

Hello,

I came across 2 different formulas for arcsin transformation of proportions (0-1) in excel:
1. =ASIN(SQRT(appropriate cell))
2. =ASIN(SQRT(appropriate cell/100))*180/PI()

What is the difference between the two?
Which one is to be used for proportions (0-1) when applying parametric statistics?

Thanks,
K
