About
Kerf Calc is the construction field calculator that just works — offline, no account, no subscription. Buy it once. FEET-INCH-FRACTION, DONE RIGHT Punch dimensions the way you measure them: 8' 4-1/2" — add, subtract, multiply, divide, and read the exact result to your set fraction (1/8 to 1/64). Do real area and volume on the tape: 10' × 8' = 80 sq ft, × 4" = 26.67 cu ft. EVERY TRADE, ONE APP • Framing — rafters (actual cut: line + overhang − ½ ridge, plus hip/valley/jack), stairs to IRC/IBC code with live riser/tread/headroom checks, right-angle & pitch • Concrete — slabs, footings, columns: yards, bags, ready-mix trucks, control joints, plus a waste allowance • Rebar — ASTM A615 sizes, weights, slab-mat, laps • Materials — roofing squares, drywall, paint, block, brick, mortar, pavers, board feet, compound miter • Convert — feet-inch ↔ decimal ↔ metric (NIST-exact) SHOWS ITS WORK Every calculator shows the actual formula and the code or standard it cites (IRC, ASTM, NIST, ACI, NCMA, framing-square tables) — so you can trust the number, not just take it. BUILT FOR THE JOB SITE Sunlight-readable light design, glove-sized keys, works with zero signal. iPhone, iPad, and Mac. Not certified engineering — a field calculator. Verify against your locally adopted code.
