Original sentence: As an inch is exactly 2.54 centimeters, or 127/50, when divided by 127 the inch is broken down into an integer times a power-of-ten fraction of the meter (2×10-4 m).Multiplying these together gives 127×72×100 = 914,400 units per inch (the least common multiple would work as well which would have been 228,600 per inch and 90,000 per centimeter).To accurately represent (with an integer) 1 μm = 10-6 m, a divisor of 100 is needed.To accurately represent a point measure, a divisor of 72 is needed, which also allows divisions by 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 to be accurate
Edited sentence: As an inch is exactly 2.54 centimeters, or 127/50, 1/127 inch is an integer multiple of a power-of-ten fraction of the meter (2×10-4 m).Multiplying these together gives 127×72×100 = 914,400 units per inch; this also allows exact representations of multiples of 1/100 & 1/32 inch.To accurately represent (with an integer) 1 μm = 10-6 m, a divisor of 100 is further needed.To accurately represent the point unit, a divisor of 72 is needed, which also allows divisions by 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 to be accurate
