A practical construction calculator for carpenters, builders and contractors. Work out concrete quantities, stair dimensions and baluster spacing from the measurements you already have. Whether you're framing a wall, planning a deck or estimating a concrete pour, Calc Tools brings 16 everyday calculators together on your iPhone and iPad. Choose a tool, enter your dimensions and get a clear result with a diagram to guide your measurements. PLAN YOUR NEXT JOB • Concrete: estimate slab volume or concrete for round posts, holes and circular pads, including a waste allowance. • Stairs: find riser and tread counts, riser height, total run, pitch and an overall stringer-span estimate. • Balusters: work out a count and equal clear gaps from your span, baluster width and maximum gap. • Decking: estimate board count and total purchase length with an allowance for waste. • Gravel, soil and asphalt: estimate volume for paths, beds and other projects. Use your chosen density to calculate gravel or asphalt weight. CHECK DIMENSIONS AND LAYOUTS • Check Square: find the diagonal, area and perimeter for a rectangular layout. • Right Triangle: solve missing sides and angles from the measurements you know. • Pitch: calculate slope and angle from rise and run. • Equal Spacing: lay out evenly spaced points by count or target spacing. • Raked Wall: calculate full wall heights at stud positions from heights or pitch. • Running Dimensions: turn a starting measurement and interval into a list of layout marks. • Dumpy Level: calculate reduced levels from benchmark and staff readings. • Area: calculate rectangular area with an optional waste allowance. METRIC AND IMPERIAL MEASUREMENTS Work in millimeters, meters, inches, or feet and inches. Enter mixed fractions and choose inch display accuracy from 1/2 to 1/64. Convert your entered measurements between units while retaining their full calculation precision. READY WHEN YOU NEED IT Calculations work offline.
