The graduations on these rules are engraved for permanence and are clear and easy to read. One edge has imperial graduations in 1/16ths, 1/32nds and 1/64ths, and the other edge has metric graduations in 0.5mm and millimetres. The reverse side of the two shorter rules are engraved with imperial only graduations whilst the longest features metric to imperial conversion tables. This pack of three rules comprises a 150mm(6") rule, a 300mm(12") and a 600mm(24").
