Ideal for faster more accurate material estimates (view larger).

Get professional results every time with the handy, easy-to-use tool Measure Master Pro measurement conversion calculator (model 4020) from Calculated Industries. It's ideal for designers, craftsmen, tradespersons, fabricators, woodworkers, and technicians for on-the-spot calculations, and it fits easily in a pocket, briefcase, or tool pouch.

Built-in functions make the Measure Master Pro ideal for faster, more accurate material estimates. Work in and convert between dimensional formats including feet-inch-fractions, decimal feet-inch-fractions, yards, meters, centimeters and millimeters as well as areas and volumes. You'll also be able to quickly find board feet for lumber estimates and solve for circumference, circle area, and arcs.

Other features include solving for cost per unit, a "paperless" tape that lets you review the previous 20 entries to double-check your totals, ability to store preferred fractional values and dimensions, and work with standard calculations.

It's powered by two LR44 batteries, and the Measure Master Pro has an auto shut-off feature that turns the calculator off after about 8 to 12 minutes of non-use. The calculator measures 2 x 5.6 x 0.6 inches, weighs 4.5 ounces, and comes with a hard protective cover. It's backed by a one-year limited warranty.
