Hands-free pipe math! Speak queries directly to our on-device AI assistant and hear spoken answers on the job site. Now with enhanced metric volume conversions.
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.
