Default Offset / Backspacing???

I have a set of Fikse FM10s I am selling and I measured from inner hub to the inside edge of wheel using straight edge. Fronts were 17.5cm and rears 20.9cm. How does that calculate in MM? (how I normally see them listed) Thanks in advance. Wheels are 17x9.5 front and 18x10.5 rears.

Thanks for the reply but that isn't actually how to measure backspacing. There is a formula or something based on the measurement from hub to inside lip and other measurements. I just can't find it.
