Chalk vs Bench Math

Type feet, inches and fractions the way you say them. Chalk's keypad takes 5 ft 3 1/2 in on one line, with one-tap fraction keys for 1/2, 1/4, 1/8 and 1/16, and answers in feet, inches and fractions. No decimal-feet guesswork and no converting in your head. Add, subtract, multiply and divide measurements on the tape calculator, then let Chalk do the job math. Every result rounds to the fraction precision you pick, down to 1/64 of an inch. THE TOOLBOX • Stairs: risers, treads, stringer length, angle and a code check • Rafters and Roof: common and hip or valley lengths from span and pitch • Concrete: slabs, footings and post holes, with bag counts • Framing and Studs: stud counts and plate lineal for any wall • Drywall: sheets, screws, compound and tape • Tiling: tiles, adhesive and grout, waste included • Brick and Block: US, UK and AU sizes, plus mortar • Decking: board rows, lineal length and fasteners • Board Feet: lumber volume and cost • Equal Spacing and Balusters: even layouts that meet code • Aggregates: gravel, sand, soil and asphalt by volume and weight • Running Measurements: layout tables from a start point and interval • Chalk Pad: a full-size dimensional calculator with memory and rise, run, pitch, diagonal, hip, jack and stair keys • Free tools: tape calculator, triangle solver, square footage and volume, pitch and slope, square check and a unit converter METRIC WHEN YOU NEED IT Working from a metric plan?
