GasCalc is a dedicated calculation toolkit built for qualified plumbers and gasfitters across Australia and New Zealand. It is designed to handle the complex maths required by industry standards, giving you reliable, accurate answers while on the tools.
Built for the Trade
"Holding unrestricted G-Class (Type A) and I-Class (Type B) licenses across multiple jurisdictions, I built GasCalc because I needed a fast, reliable way to run complex commercial and industrial calculations out in the field. It started as a practical tool to speed up my own workflow and ensure absolute accuracy. I’ve made it available because I believe it's a utility the rest of the trade can rely on."
Anchored to the Standards
Every calculator within GasCalc is hardwired to the rules we work by. The formulas and reference data are derived directly from authoritative sources:
Where standards are referenced, the app provides the exact standard and clause number. This gives you a clear, immediate path back to the official documentation whenever you need to verify a requirement.
Professional Documentation
GasCalc goes beyond just providing the numbers. The app takes your on-site data and generates clean, standardized PDF reports. Whether you are handing a safety audit to a client or Type B submission to an Inspector, your paperwork stays sharp, accurate, and ready to send.
A Tool, Not a Replacement
GasCalc is an advanced supplementary tool designed to do the heavy lifting on fixed mathematical formulas.
The app operates deterministically, utilizing fixed algorithms based strictly on pre-programmed industry formulas. It acts as a specialized calculator.
This tool is intended to drive users toward the official standards as the primary source of truth. It does not replace official compliance documentation, nor does it replace the professional judgment of a licensed gasfitter on the ground.
