ade from solid brass, this very handy pocket vernier caliper features permanently engraved graduations in both metric and imperial units.

Calipers without a vernier scale originated in ancient China. The secondary scale, which contributes extra precision, was invented in 1631 by Pierre Vernier, a French mathematician and instrument inventor. Readings from a vernier caliper are expressed to two decimal places of a centimeter. The main scale contributes the main number and one decimal place, the vernier scale contributes the second decimal place to the reading.
