Font Size Unit Converter

Using Font Size Unit Converter

Convert px, rem, em, pt and percentages using explicit root and parent font sizes.

Enter a size and choose px, rem, em, pt or percent. Set the root and parent font sizes explicitly to match the page you are working on.

The result table uses the CSS relationship of 96 pixels to 72 points. Rem is relative to the root; em and percentages use the parent value supplied here.
