InchCalc: Feet Inch Calculator

Feet-inch fraction math that thinks like a tape measure. A paper tape you can go back and fix, plus concrete, board feet, and wall framing estimators.

One-time purchase. No subscription.

InchCalc is a feet-inch-fraction calculator built for the job site: framing, concrete, decks, cabinets, and everyday tape-measure math.

WORK THE WAY YOU MEASURE

• Enter 5 ft 3 1/2 in directly: big high-contrast keys for gloves and sunlight
• Add, subtract, multiply, divide feet, inches, and fractions without converting
• Results in fractions of an inch (1/16, 1/32, 1/64 precision), decimal inches, decimal feet, or metric (mm / cm / m) with one tap

PAPER TAPE THAT THINKS

• Every calculation is saved to a running tape
• Tap any line to reuse its result in a new calculation
• Pro: edit or delete any past entry and dependent results recalculate

MATERIAL ESTIMATORS (Pro)

• Concrete: slab volume in cubic yards
• Board feet: lumber quantities from dimensions

BUILT FOR THE TRADES

• Memory keys (M+, M-, MR, MC) and instant unit conversion
• No account, no tracking requirements, works fully offline
• One-time Pro unlock: material estimators, tape editing, and ad removal
