CSS font-size units PX to PT, IN, EM, REM conversion

I need to calculate how many Pixels are in 1 Point and other CSS units. For example how can I convert 11 pixels into points, or 12 points into pixels ?

Hi,

You can convert font size by the following calculations:

1 Pixel = 0.75 Point
1 Point = 1.3333 Pixels
1 Pixel = 0.010416666 Inches
1 Inch = 96 Pixels

Font size units Em and Rem are relative to other font sizes. Em is related to font size of the parent element. Rem is related to font size of the root element. For example, if the size of parent element is 16px, then 1.5 em is equal to 24px. When the size of root element is 18px, then 1.5 rem is equal to 27px.

To convert font sizes, you can also use this table:
