Method of Calculation
The measurements generated for columns two through four presented
in the following tables are derived from the millimeter column. To calculate
the inches for the second column, the millimeters were multiplied by .03937
and divided by twenty. A pica point is equal to 1/72 of inch or .013888
inch. The figures were calculated by multiplying by millimeters by 2.83482
and dividing by twenty. The Fournier point is equal to .013728 of an
English inch while the didot point is equal to .0148 of an inch; millimeters
were multiplied by 2.6601 and divided by twenty. A consistently high
degree of mathematical accuracy for the calculations has been assured by
using "1-2-3," Release 2.01 from the Lotus Development Corporation. To
check these calculations, note that 508 millimeters per twenty lines equals
1.0000 inches or 72.00 pica points.
