Hello Sam,

You can find out the PNU/inch rate yourself: Load a promitive and translate it exactly 1.000 PNU in any direction. Now switch the units to inches and see what the dial reads now. That's the exact value.

However, I think working with smaller-scale units is better. Poser produces rounding errors in the last one or two decimal places when saving or loading (that's why you sometimes see dials which have a value of -0,000). So the less decimal places are necessary for maximum precision the less this matters.
