In TeX `1pt`

(**TeX point**) is defined as 1/72.27 inch. Many other applications like Word and Adobe InDesign etc. however use a slightly bigger point – defined as 1/72 inch – the **DTP** or **PostScript Point**. In TeX this unit is named Big Point: `1bp`

This is incorrect. When Warnock and others developed PostScript, they defined the PostScript point as 1/72-inch. This can be verified by reference to the “PostScript Language Reference”, third edition, page 183.

Thanks for your hint! It was already corrected in the overview (the download) but I forgot to change it here in the post, too.
