If someone could explain to me how:

baseline / 2&pi × distance = parallax / 360°

becomes:

distance = baseline × (360°/2&pi) / parallax

I would be forever grateful. For some reason I am unable get my head wrapped around reorganizing this equation.
Who does she think she is?

Heh - sorry about that! Brain bleach is sounding good right about now.

Why does the equation use two different units like that? 360° is the same as 2pi.

Oh yeah, so then (360° / 2pi) = 1.

The equation can be written:

b / (2pi * d) = p / 2pi

Multiply both sides by d to get

b / 2pi = pd / 2pi

Multiply both sides by 2pi / p to get

b / p = d

Isn't 2&pi radians = 360°? with 360°/2&pi equalling 57.3°?

You can't divide degrees by radians without converting one or the other unit.
