Offsets
Pipe Offset Calculator
Travel and run for 11¼, 22½, 30, 45 and 60° offsets, with the multipliers.
Rolling Offset Calculator
True offset, travel, run and roll angle from rise and roll. Or the fitting angle for a set run.
Parallel Offset Calculator
Several pipes through the same offset: where each next one starts so the spacing stays equal.
Cuts & fabrication
Pipe Cut Length Calculator
Center-to-center minus fitting take-outs and weld gaps. Plus take-out of an elbow cut to any angle.
Mitered Elbow Calculator
Segmented elbow from straight pipe: cut angle, segment lengths (long and short side) and take-out.
Measure & convert
Pipe Slope Calculator
Fall over a run at ¼", ⅛" or any slope per foot, or the slope from a measured drop. IPC minimums.
Feet-Inch Calculator
Add, subtract, multiply and divide feet, inches and fractions.
Right Triangle & Squaring Calculator
Rise, run, diagonal, angle and pitch; diagonals and 3-4-5 for squaring.
Construction Unit Converter
Convert feet, inches, meters, sq ft, acres, cu yd, gallons, pounds, tons and more.
Bubble Level
Phone level and inclinometer: angle, slope % and rise per foot.

Rise (ft)
Examples: 12', 5' 3 1/2", 3/4", 2.5m
Run (ft)
Examples: 12', 5' 3 1/2", 3/4", 2.5m
Diagonal (ft)
Examples: 12', 5' 3 1/2", 3/4", 2.5m
Enter any two of rise, run and diagonal.
Angle is measured between the run and the diagonal. Pitch is rise per 12 of run. Estimates only. Check measurements, product labels and local building codes before you buy or build.
