Fraction, feet-and-inch, concrete, roof rafter and stairs math for the jobsite — precise to 1/16", fully offline, no internet needed. Construction Calculator is a fast, offline-first calculator built specifically for the jobsite — no more converting fractions in your head or guessing at concrete yardage. FRACTION & FEET-INCH MATH Add, subtract, multiply, and divide fractions and feet-and-inch measurements directly, with results rounded to the nearest 1/16 of an inch — the precision framers and finish carpenters actually need. CONCRETE CALCULATOR Enter your slab, footing, or column dimensions and get the concrete volume you need to order, without pulling out a separate reference chart. STAIRS CALCULATOR Work out rise, run, and stringer measurements for a code-compliant staircase in seconds. UNIT CONVERTER Convert between millimeters, inches (as feet-and-inches fractions to the nearest 1/16"), and hundredths-of-a-foot (engineering feet) with a guided, tap-based flow — enter a value, pick your target unit, and get your answer instantly. Built for contractors, framers, concrete crews, and anyone who needs precise, practical measurements on-site — no internet connection required.
