9/16 = 18/32 = 36/64

All the same mark. 9/16 is the form in lowest terms, which is how a rule labels it and how a cut list should read.

Converting 9/16 to a decimal

A fraction is a division. 9/16 = 9 ÷ 16 = 0.5625. The decimal terminates because 16 factors into 2 × 2 × 2 × 2 — only 2s and 5s, the factors of ten. Any fraction whose denominator is built from those has an exact decimal.

In metric that is 14.2875 millimetres (1.42875 cm), since one inch is exactly 25.4 mm. As a percentage of an inch it is 56.25%.

9/16 is a real mark on a rule: it is the 9/16 mark on a 1/16 rule, and the same mark is written 18/32 or 36/64 at finer precisions.
