In the American point system:1 pica = exactly 0.1660 inch (versus 0.1666 = 1/ 6 inch for the DTP-pica) = 4.216 400 mm.1 point = 1/ 12 traditional pica = exactly 0.013 83 inch = 0.351 36 mm.The American point system has been used in the USA, Britain and many other countries including Japan.Today, digital printing and display devices and page layout software use a unit that is different from these traditional typographic units. On many digital printing systems (desk-top publishing systems in particular), the following equations are applicable (with exceptions).1 pica = 1/ 6 inch (British/American inch of today) = 4.233 mm.1 point = 1/ 12 pica = 1⁄72 inch = 127⁄360 mm = 0.3527 mm.en.wikipedia.org/wiki/Typographic_unit
