Some references state that the size of a printer's point in the English-speaking world was defined in 1886 on the basis of 83 picas being equal to 30 centimeters.
Other sources state that while this was one of the proposals considered, the one actually adopted was the Johnson pica, which based the point on 1/72nd of 249/250ths of the British inch, not the American one, which still differed at the time.
Neither of these standards, though, equal 0.013837 inches, which many sources give as the official printer's point.
I've seen only one place on the Web acknowledging this discrepancy: a conversion table from Circuitous Root, which credits ATF with the modern printer's point as of 1902.
