It is a form of font-size measurement. Unlike px, which is relevant to the device (hence why fonts on MAC, Linux and Win look different - even though their 'px' size is the same). Instead, em is font-size relevant to the font.
In this case, using em is a more ideal choice for usability...since it will scale accordingly. Although, unfortunately, it doesn't work as well as it should.
