What is Point to REM Converter?

Point (pt) is the standard typographic unit in print design. REM is the modern CSS unit for scalable screen layouts. At the browser default of 16px, 12pt = 1rem.

The formula is: **rem = pt × (4/3) ÷ base**. This makes it easy to take a print design spec and translate each size to a REM value for the screen stylesheet.
