I also do similar things and  what I used to do is

- to choose  glyph type sphere
- Scalar   radii
 - *set Radius as 1* (in the Sphere tab just after Center property)
- select scale mode scalar
- *set scale factor 1
*
Then it should correspond to real values...
Hope other would correct me if I am being wrong here
