PipeFitter: Offset Calc

PipeFitter is the offset calculator built for pipefitters, plumbers and steamfitters. Work in feet, inches and fractions — the way you measure — and get travel, run and cut length in seconds.

SIMPLE & ROLLING OFFSETS
- Enter the set (offset) and pick a fitting angle: 45, 30, 22.5, 11.25, 60 or 72 degrees, or any custom angle.
- Rolling offset from a rise and a roll, with the true offset and roll angle figured for you.
- See the travel and run multipliers (cosecant and cotangent) for the angle you chose.

CUT LENGTH
- Subtract the fitting take-out (center to face) from the travel to get the exact pipe cut length.

GRADE & SLOPE
- From a run, get the drop, slope angle, drop per foot and ratio. Common grades built in (2% ADA, 1/4 in per foot, and more).

MADE FOR THE JOB SITE
- Big, high-contrast numbers that read well outdoors.
- Fraction precision from 1/8 down to 1/64 inch.
- A quick reference of the offset multipliers.
- Works completely offline, with nothing to sign in to and no data leaving your device. No ads.
