  6. 62,5% em px in css as body element size for text improvement/addition works great for me now now, in all browsers it’s the same. Before I could see several differences in mainly text on pages.

    Bodyelement 10px at 62,5%/em = 100px ;
    And 10em at 62,5%/px = 0.63em – 63/100em ; ie. is the base calculation I worked from and all works for 100%.

  8. Nice tool, though it might have added value if you explain a bit about pixel-to-em conversion and what calculation factor you use. I.e., on Mac, the PPI is 76 and on modern Windows, it is 96. Older Windows has 72 by default. Obviously, local user settings can override this.

    In addition: why the preset of 62.5%? Would be nice to add a percentage ourselves!

  10. I couldn’t figure out my sidebar width from 250 pixels to em number. I had to add 1px to the exact width of my vertical sidebar, because of 1px thin border on 2 sides. Only height was correct, I have “high: 100%;” coded in css file. 248 px for the sidebar plus 2 times 1px design borders added to width. This px to em converter calculated for it to work exactly. 250 px ( Pixels ), Equals = 15.6 em
