JOIXTCALCULATOR
joixt

A tape-measure calculator.

Type 3 5/8 + 1 7/16 the way you'd say it. Get live answers in fractions, decimal, millimeters, and feet-and-inches — at the tape-mark denominator you choose. Save named variables (kerf = 3/32), tag results to projects, and reach the offline reference library when you need a Kreg chart or nominal-vs-actual lumber table.

Fractions, natively
Accepts 3 5/8, 3-5/8, 92mm, 2' 4 1/2", and decimal — round-trips between them.
Pick your tape
Toggle the tape-mark denominator from 1/2 through 1/64. Every answer rounds to a mark you can actually find on your blade.
Variables you re-use
Define kerf = 3/32 once. Reuse it in any expression. Sync across your devices.
Specialized functions
Board feet, polygon & compound miter, drawer-box dimensions, equal divisions, sagulator, shrinkulator — all fraction-aware.
Offline reference
Kreg pocket-screw chart, lumber nominal-vs-actual, drill / clearance / countersink sizes, sandpaper grit progression, finish coverage, EMC by region.
Shop Mode
One tap flips the screen to a high-contrast, glove-friendly walnut-on- charcoal layout for low-light shops.
