Are theta units in Scherrer's equation degrees or radians?

hi
is theta used in degree or radians in Scherrer's equation..

What appears is not $\theta$ but $\cos \theta$. It should be rather clear how this is to be interpreted.

 

[Humaira Khalil]

we need to take cosine of "THETA". Is it measured in degrees or radian,,, what is think is theta is in degrees, but confused...

 

[Orodruin]

Do you understand what the cosine function does?

YESS! actually I'm analyzing XRD results, from Origin Software... to find FWHM this theta is required...

 

[Orodruin]

YESS!

Then you should already know the answer to your question.
