Pourwright is a concrete and masonry calculator for concrete finishers, masons, contractors, estimators and do-it-yourselfers. It works like a hardware calculator: a concrete-grey chassis, real keys and a clear LCD, with each answer labelled so you know what you are reading. VOLUME • Slabs, footings and walls: length × width × thickness × quantity • Round columns, piers and tubes from diameter and height • Solid steps to grade from width, riser, tread and number of steps • Cubic yards and cubic feet, or cubic metres and litres, with a waste percentage you set (5 % until you change it) • Weight at 150 lb/ft³ (2400 kg/m³) BAGS AND READY-MIX • Premix bag counts for 80, 60 and 40 lb bags, or 25 and 20 kg bags • Ready-mix order rounded up to the next ¼ yd³ (¼ m³) REBAR • Two-way grid for a slab: bars each way for a spacing and edge cover • Bar lengths, total length and weight • US #3 to #8, Ø8 to Ø25 mm and 10M to 25M bars BLOCK AND BRICK • Wall area from length and height, less doors and windows • 8×16 in or 440×215 mm block counts, modular or 215×65 mm brick counts • Typical mortar bags for the wall WORKS THE WAY YOU DO • Feet and inches or metres and millimetres • A results strip shows every solved value at once • 10 memories, a tape of your calculations, reference tables (rebar, bag yields, masonry, concrete weight) and a key guide FREE TO TRY, THEN UNLOCK ONCE Free to try: every feature for 7 days.
