Pourwright Concrete Calculator

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
• Export a job strip: the tape with inputs, stamped and ready to attach to a lift plan, sign-off or take-off, as text or PDF
