What is Point to EM Converter?

Point (pt) is a typographic unit used in print design. When converting pt to em for screen CSS, you need the parent element's font size in px. At the 16px default, 12pt = 1em.

The formula is: **em = pt × (4/3) ÷ base**. This is useful when translating print typographic specifications to responsive screen CSS.
