These professional quality rulers from Pacific Arc are constructed of stainless steel and feature acid etched graduations to ensure maximum accuracy and durability. The front of each ruler features inches on one edge, and metric on the other. These rulers also have a handy conversion table (from inches to millimeters) etched into the back, as well as a non-slip strip.

Inch graduations are every 1/16 in. (every 1/32 in. up to 3 in. and every 1/64 in. between 3 and 4 in).
Metric gradations are every mm. (every half mm. up to 10 cm).
