Type feet, inches, and fractions exactly like they appear on your tape. Plumb handles the carries, conversions, trade estimates, markups, and cut lists offline.
Feet, Inch, and Fraction Calculator
Plans, tape measures, studs, rafters, sheet goods, and pipe are not decimal. They are feet, inches, sixteenths, thirty-seconds, 16-inch centers, 4x8 sheets, and 12-inch roof runs.
Plumb removes the decimal translation tax so pros can calculate in the same units they measure, cut, and order.
Standard Calculator
Every translation is another chance to cut wrong.
