Why these five units

Screens speak pixels, US print speaks inches, metric print speaks centimeters and millimeters, and type has spoken points for centuries. Work that crosses those worlds (a web layout going to print, a font size becoming a physical measurement, an image file with a DPI header) needs the conversions constantly, and each pair behaves like its own question, so each pair gets its own page here with its formula, its table and its worked examples.
