Basically 1em equals the inherited font-size on the current element. You can set font-size for your body element, and have all other elements use 'em' in their font-size and it will be relative to the size you set in the body.

Without ancestor magnification, 1em is exactly equal to the pixel font-size attribute. Warning A major caveat to 2 is that the relative ratio of the ex unit is wildly unstable. In the same browser with constant font, the relative ratio can change with font size. The relative ratio of ex also changes with the browser even with the same font size and browser safe font such as Georgia.

This is a pretty good reason not to ever use the ex unit if you want conformity. If the ex unit is used, it is impossible to compute the font-size through the ancestor chain.
