A snippet pipe that will calculate ems based on a given pixel value and base unit.

E.g. If you want a 10px font-size expressed in ems, you would need to perform the following calculation (note 16px is the default base font size in all browsers):

10px / 16px = 0.625em

This snippet allows you to specify the desired pixel size and the base font size and will return the calculated em value.

Copy this code and paste it in your HTML
  1. ${0:calculate ${1:10}px in ems with a ${2:16}px base|
  2. ruby -e "print (ENV['TM_TABSTOP_1'].to_f/ENV['TM_TABSTOP_2'].to_f).to_s + 'em'"}
