Stainless Steel Ruler 300mm 12in Inch/mm Conversion Table

A 300mm stainless steel rule for accurate measuring and marking out across workshop, garage and DIY jobs. The clear dual scale gives both 12in and 300mm readings, with an inch/mm conversion table on the rule for quick reference while you work.

Used for general measuring tasks, this steel ruler suits bench work, fitting, light fabrication, home maintenance and everyday repairs where a straightforward straight-edge is needed. Handy for marking materials before cutting or drilling, checking dimensions during assembly, or keeping close by for vehicle maintenance and workshop use when switching between imperial and metric measurements.

The stainless steel construction gives the rule a durable, practical finish for repeated use, while the slim profile makes it easy to store in a toolbox, drawer or bench area. The 300mm / 12in length is a common size for routine measuring jobs, giving enough reach for many day-to-day tasks without being awkward to carry. Having both scales on one rule helps when drawings, parts or measurements are given in different units, and the printed conversion table is useful for reducing guesswork during regular measuring and marking work.
