Construction Calculator ft/in

A construction calculator in feet, inches, and fractions. Enter a slab 24 ft 6 in by 12 ft 3 in by 4 in and get cubic yards plus 80 lb and 94 lb bag counts.

Built for people who measure to the sixteenth and order in whole bags. Add and subtract feet-inch fractions without turning them into decimals in your head, then use that length on the next takeoff.

What you can figure:
- Slab, footing, post hole, stairs, deck, gravel, paint
- Concrete by cubic yard, with 80 lb and 94 lb bag counts
- Drywall sheets and board feet
- Rebar weight, plus a bar schedule that tells you how many stock bars to buy and how much offcut is left
- Form contact area, scaffold and prop counts
- A plywood order where you type the nails on each sheet
