There isn't a way that I know of, however, they may be an alternative solution:
Specify your measurements in 'pt' and 'em', which are screen relative metrics.

- em:
1em is equal to the current font size. 2em means 2 times the size of the current font. E.g., if an element is displayed with a font of 12 pt, then '2em' is 24 pt. The 'em' is a very useful unit in CSS, since it can adapt automatically to the font that the reader uses
- pt:
point (1 pt is the same as 1/72 inch)
- pc:
pica (1 pc is the same as 12 points)
