qbCalculator: Feet Inch Calc

qbCalculator is a construction calculator built for the job site. Type feet, inches and fractions the way you read them off the tape, mix metric and imperial in one line, and get a number you can cut to. Built by people who work in renovation, interior design and carpentry — for contractors, carpenters, cabinet makers, tilers, interior designers and site engineers. FEET, INCHES & FRACTIONS • Enter feet, inches and fractions directly — no converting to decimals first • A real fraction calculator: type numerators and denominators as they are • Write the whole expression in one line instead of working it out step by step MIX UNITS IN ONE CALCULATION • Add millimetres to inches, or feet to metres, in the same formula • Length: m, cm, mm, ft, in, yd • Area: m², ft², in², cm², mm², acre • Volume: m³, ft³, in³, L, mL, gal • Weight: kg, g, lb, oz YOUR OWN FORMULAS • Save the formulas you use every day — tile quantity, paint coverage, concrete volume, cabinet panel sizes • Give each variable a name, then just fill in today's measurements • No more retyping the same long equation on every job FLOATING CALCULATOR • A small calculator window that stays on top of your drawings, WhatsApp or PDF plans • Collapse it to a bubble or adjust its transparency • Shares the same expression, answer and history as the main screen MORE TOOLS FOR SITE WORK • ANS key carries your last result into the next calculation • Calculation history you can go back to • Cloud backup: sign in and your formulas, history and settings follow you to a new phone • Clear display in bright sunlight and dark rooms WHO USES IT • Carpenters and cabinet makers working out panel sizes and cut lengths • Renovation contractors estimating tiles, paint, plaster and concrete • Interior designers converting between metric drawings and imperial materials • Engineers and site supervisors checking measurements on the spot • DIY homeowners who are tired of converting fractions by hand A phone's built-in calculator cannot add 3/8 inch to 2 feet, and it cannot remember your formulas. qbCalculator can.
