Rolling offsets, simple offsets, drainage grade and cut lengths — all in feet-inches-sixteenths — on a keypad built for gloved hands. No subscription. Works offline. Pipe Offset Calculator gives plumbers and pipefitters the four calculations they run every day — rolling offsets, simple offsets, drainage grade, and end-to-end cut lengths — with huge type you can read across the trench and a fraction keypad built for a tape measure, not a spreadsheet. No subscription. No account. Works offline. Your data never leaves your device. ROLLING OFFSET Enter the set (or rise) and roll, pick your fitting angle — 22½°, 30°, 45°, 60°, 90°, or any custom angle — and get true offset, travel, and run instantly, with a labeled diagram so you always know which number is which. SIMPLE OFFSET Single-plane offsets: one measurement in, travel and run out, drawn to your actual fitting angle. GRADE Drainage slope both directions: run + grade gives you the drop, or run + drop gives you the grade — in inches-per-foot and percent, with one-tap presets for 1/8″, 1/4″, and 1/2″ per foot. CUT LENGTH & REFERENCE A plain-English takeout explainer, standard butt-weld elbow takeout rules, and a cut-length calculator: travel minus both fitting takeouts equals the pipe you actually cut. Plus a full sixteenths decimal-to-fraction table. BUILT FOR THE JOBSITE • Every measurement works both ways: feet-inches-sixteenths AND decimal inches — enter either, read both (27-3/16″ and 27.19″) • Custom fraction keypad with 1/16″ steps and ±1/16″ nudge buttons • Big result cards — tap any result to copy it • Your numbers are saved automatically, per tab • One-handed layout, haptic feedback, full dark mode • 100% offline — works in the basement, the crawlspace, and the parking garage Buy it once, use it every day.
