A twip is a typographic unit equivalent to 1/20 of a printer's point or 1/1440 inch, used for fine layout precision in text and GUI positioning.

Why convert twips to millimeters?

Converting twips to millimeters allows integration of typographic measurements with metric units commonly used in engineering, manufacturing, and CAD.

Is the twip unit still widely used?

Twips are mostly used in legacy computing and desktop publishing contexts and are less common in modern native user interface frameworks.
