## What is Construction Calc?

Construction math that works the way tradespeople do. Onsite Math handles feet, inches, fractions, decimals, and metric values without forcing you to convert everything first.

CALCULATE WITH CONFIDENCE
• Add, subtract, multiply, and divide mixed dimensions
• Choose precision from 1/2 through 1/64 inch
• Convert imperial and metric results instantly
• Keep a readable running tape of every calculation

A COMPLETE FIELD TOOLKIT
• Stairs, common rafters, roof triangles, and equal spacing
• Architectural and metric plan-scale conversion
• Concrete, drywall, tile, paint, lumber, roofing, block, and rebar estimates
• Waste, tax, labor, currency, and unit-cost support

BUILT AROUND REAL JOBS
Save calculations and estimates under named jobs, then create a clean PDF report for your client, crew, or records. Everything works offline and job data stays on your device.

The fraction calculator and unit converter are free. Unlock the complete professional toolkit with one optional lifetime purchase. No subscription, ads, account, or third-party analytics.
