There’s also bp (big points). We have the difference between TeX  
points (pt) and PostScript points (bp) in ConTeXt like in every other  
TeX:
1 pt = 1/72,27 in = 0,3515 mm (traditional American printer’s point)
1 bp = 1/72 in = 0,3528 mm (after the Anglo-Saxon compromise inch of  
1959 = 25.4 mm)
(1 "Didot" point, traditionally used in Europe, was 0,376 mm)
