## What is Construction Calculator?

Built for the job site: Construction Calculator A1 turns the math you do every day — concrete orders, rebar takeoffs, feet-inch measurements — into a few taps.

FEET-INCH & FRACTION MATH
• Add, multiply and divide in feet, inches and fractions down to 1/16"
• Unit-aware: 3 ft × 4 ft = 12 ft², mixing metric and imperial freely
• L / W / H memory keys, cost math with %, history and one-tap copy

CONCRETE
• Mix designer for M10–M50 grades: cement bags, sand, aggregate and water
• 6 pour geometries — slabs, columns, footings or direct volume
• Dry-volume factor and total weight built in

STEEL & REBAR
• Slab, column, beam and footing reinforcement with CAD-style section details
• Bar weight, spiral/helix rebar, BBS shape codes (BS 8666:2020)
• Honest estimating notes — check final quantities against your bar schedule

AREA · VOLUME · CONVERT
• 19 area shapes and 17 volume shapes with clear diagrams
• Surface area and material-to-weight conversion
• 40+ unit converter categories with favorites and copyable results

PROJECTS
• Save any result to a project with inputs and date
• Length, area, volume and cost totals per project
• Share a text summary in one tap

Metric and imperial everywhere. No account needed. Works offline.

Whether you're a contractor, estimator, civil engineer, mason, carpenter or a weekend builder — if your tape measure sees daily use, this calculator belongs next to it.
