What is Percent to Point Converter?

CSS percent for font-size is relative to the parent element's font size. Points (pt) are absolute typographic units used in print. Converting from percent to pt requires a base px size: **pt = (% ÷ 100) × base × 0.75**.

At the 16px browser default: 100% → 16px → 12pt. This conversion is useful when you need the print point equivalent of a percent-based CSS font size.
