I added a goodie that does em to px conversion per the request here:
created em_to_px converter
fix regex and usage syntax
Searching for "8px in px" or "27em to em" would return a wrong value... It's stupid but we should think about every possibility.
I didn't think "em to px" is a valuable conversion at all, as its relative entirely on the fontsize used .
@kentfredric: like in http://pxtoem.com/ ?
Maybe we should default to some pt size and suggest syntax to specify a different pt size?
@kentfredric - we are assuming a default of 16px for now (that gets it started, may add the ability to change default size later). I am also working on adding conversions to and from points as well as em and px
@elektronikLexikon - you are correct and I will handle that as well
@kentfredric Sure it's relative, but browsers have a default font-size of 16px. Going from that can still yield helpful results. Maybe we can come up with a sensible query syntax to specify the base font size.
About to go live -- I added a parenthetical note about the base front size choice.
