It's the distance between the eyes.
It's about 13 cm usually, for adult human at least.
I do not know if you have a scale setting for your scene. (something like: 1 pov unit
= x.xxx meter )

If you have a "focus" point, it might help.
Focus point is on the line from 'location', along 'direction'.

Here attached is an illustration of distance and parallaxe.

Value of parallaxe is in radian.

It's the angle away from the direction vector for each pseudo-center for the image of
each eye.
