Westcott M-109 Metric/Inch Ruler 30cm Opaque

The Westcott M-109 Metric/Inch Ruler is a practical measuring tool that combines metric and imperial scales in a single 30cm (12-inch) instrument. One edge is marked in millimeters while the opposite edge is divided into sixteenths of an inch, with the two scales meeting at the center of the ruler for direct comparison. This layout is useful for anyone who regularly works with both measurement systems — whether converting between dimensions on imported drawings, checking specifications listed in different units, or simply needing a versatile general-purpose ruler.

Made from lightweight laminated plastic, the M-109 is built to handle daily use in classrooms, studios, and offices without adding weight to a pencil case or tool kit. Its transparent finish lets you see through to the page beneath, which aids in aligning the ruler precisely over existing lines and marks. On the reverse side, eight printed unit conversions serve as a handy reference, reducing the need to look up common conversion factors. Whether used for drafting, layout work, or everyday measuring tasks, the M-109 covers the basics reliably and affordably.
