Pinhole diameter help

Ok,
I have been doing a bit of reading but I am a bit
confused. Being that this is my first pinhole camera
I am a newbie. I figured out my pinhole diameter to
be 0.22 for a 1.5in focal length and an F-stop of 167.
 Is this right? I just don't want to screw it up and
was hoping someone on the list could maybe check my
math so to speak. I just have a funny feeling that
this is not correct.

Thanks,

Tom
