Pipe Calculator A1 Pro

Now with 60 job-site calculators: rolling offsets, take-outs, weld metal, pipe capacity and flow - each with a scale diagram and a PDF you can hand to the foreman.

Pipe Calculator A1 Pro is a professional pipe trades math calculator for pipefitters, plumbers, steamfitters, sprinkler fitters and HVAC installers. Work directly in feet-inch-fraction, metres or millimetres - no converting back and forth, no decimal-degree guesswork.

OFFSETS AND ROLLING OFFSETS • Simple offsets from any two of offset, run, travel or angle • Rolling offsets with roll, true offset and travel • Solve at 45, 22 1/2, 11 1/4, 60, 30 or any custom fitting angle • Percent grade and slope entry as well as degrees

CUTBACKS AND CUT MARKS • Fitting take-out, cutback and end-to-end cut lengths • Welder's gap applied automatically • Cut marks for a full run of fittings

PIPE MATERIAL AND SIZE DATA • Built-in tables for copper, steel, stainless, cast iron, brass, aluminum and plastic • Outside diameter, inside diameter, wall thickness and weight per foot • Filled-pipe weight and volume

FLOW, VELOCITY AND PRESSURE • GPM, litres/sec, CFM and CFS • Velocity from flow and pipe size, or flow from velocity • Pressure loss, head, force and area

60 JOB-SITE CALCULATORS, WITH DRAWINGS A second tab the handheld never had - 60 calculators across eight disciplines: Offsets & Layout, Pipe Data & Weight, Hydraulics, Drainage & Plumbing, Gas · Steam · Air, Welding & Fab, Insulation & Heat, and Estimating. • Every calculator draws a to-scale diagram of what you just worked out • Every calculator cites the standard or engineering relation behind it • Export any calculation to PDF — drawing, inputs, answers and sources • Save calculations to a job and reopen them with the numbers you entered

DIMENSIONAL MATH THAT MATCHES THE TRADE • Feet-inch-fraction arithmetic with selectable fractional resolution • Instant metric conversion - mm, cm, m • Area, volume, circle and weight/force functions • Full trig: sine, cosine, tangent and their inverses, plus D:M:S

BUILT FOR THE JOB SITE • Running tape you can name, save, print and share • Nine memory registers plus an M+ accumulator • Notes with photos, and saved calculations organised per project • Preference mode for units, fractional resolution and display format • Home-screen and lock-screen widgets for one-tap access • Dark mode, and works fully offline — no signal needed in a mechanical room

Every key is documented in the built-in Help & User Guide across twelve chapters - and long-pressing any key shows what it does with a worked example.

SUBSCRIPTION AND PRICING Pro unlocks all 60 Quantity calculators, PDF export, projects and backup. The calculator, converter, notes and a starter set of calculators in every category stay free.
