Web designers mostly use two font formats for body fonts that are pixels and em. I was always confused with em format of fonts but these days most of the web designers have started using em format. So if you are also confused with both the formats, here is an online tool to convert pixels to em.
PXtoEM.com is a online px to em converter which easily converts font format from pixles to EMs. Simply select your body font size and you will get conversions in em format based on your body font size in the next column.

but what is this em ?
According to wikipedia
It looks like em units are used to improve website accessibility, mostly on IE when you change font size in the browsers settings, when you use em’s not only font gets biger but your entire website, stopping text from running out of divs, etc. anyway, if you have to calculate entire page it may take you some time, I started with one file but that was tiring, I wrote a little program in Delphi, that calculates and replaces all values in whole code you paste. If you like you can get that from the link below (btw. save it as .exe, for I could not upload it as .exe file), let me know if you find any errors in calculations.
Yes, convert font format from pixel to EM is such a difficult thing but through the online tool it seems to be easier for us. I am very much grateful to you for sharing this . I liked it very much.
Thanks and Regards
