Job Site Calculator

Calculate rebar weight, steel cost, and concrete volume directly on the job site.

Job Site Calculator is built for contractors, estimators, foremen, engineers, and construction crews who need fast material takeoffs without spreadsheets or internet access.

Rebar tools:

• US rebar sizes #3 through #11
• Metric rebar sizes 10M through 35M
• Grade selection for US and metric standards
• Total weight in lb or kg
• Steel cost by lb, kg, ton, or tonne
• Multi-line material takeoffs
• Project name, notes, saved recent takeoffs, share, and CSV export

Concrete tools:

• Slab, footing, and column volume estimates
• Output in cubic yards or cubic meters
• Waste factor
• Optional concrete price
• Optional truck capacity and truckload estimate

Why it helps:

• Works offline with built-in tables
• Fast US and metric switching
• Large, clear inputs for job-site use
• Practical results for ordering checks, field conversations, and takeoff support

Calculations are estimates based on standard rebar weight tables and standard geometric volume formulas. Always verify project drawings, specifications, local codes, and supplier requirements before ordering or installing materials.
