I posted this on HN hoping to find an explanation. I tried all sorts of calculations, including measuring my screen size to find how many centimetres 1 pixel is

  Hovering over the <html> tag shows the site's height is 10735200px 10735200 px / (37.8px / 1 cm) = 284000 cm Based on a 96dpi standard monitor (96px/in or 96px/2.56cm)

    Small nitpick: an inch is 2.54 cm, not 2.56 cm. That makes the html element 284035.5 cm high, which I guess is the height of that "whws" div plus the height of text and margins above and below. In any case about 28.4 m is a long way of from 18.94 km.

      Oops you're right about that typo Although for css cm, browsers will use 37.8 px/cm instead of 96/2.54=37.7952 when making the conversion which gives the even 284000cm The only way I can think of to get 18.94 km from the browser's interpreted 2.84 km is if the website is physically projected/printed on a 14.4 dpi display like a billboard
