Job-site concrete volume: feet/inches in, cubic yards and bag counts out, offline.

Problem

Construction workers and contractors need a fast cubic-yard and bag count before the pour starts. Standing on site with a tape measure, they don’t want to open a spreadsheet or hunt through a website.

What it is

A concrete volume calculator for the job site:

  • Modes: slab, column, footing, post hole, tube form
  • Imperial inputs (feet / inches)
  • Output in cubic yards plus 60 lb and 80 lb bag estimates
  • Works offline

Core path is Calculate + Settings. That path is what ships solid today.

Approach

Keep the math local and the UI tight: pick a form, enter dimensions, get yards and bags. No cloud dependency for the estimate.

Outcome

Someone on the job can size the pour from their phone and keep moving.
