About Industrial Unit Converter

What We Do

Industrial Unit Converter provides free, accurate unit conversion calculators for industrial engineers. Our focus is on the conversions you actually use on the job — compressed air flow, pump head, pressure, HVAC, and process engineering — not generic kg-to-lb tools.

Each calculator is built from industry-standard formulas and reference data. Every result includes the formula used, the assumptions made, and links to related tools so you can work through your entire engineering workflow without leaving the site.

How We Build and Review Content

Every tool on this site goes through a structured editorial process:

  1. Source research — We start with published standards (ASHRAE, CAGI, ANSI/HI, ISO, SMACNA, NIST) and reference engineering textbooks to identify the correct formulas, unit conversions, and boundary conditions.
  2. Calculator development — The conversion engine is implemented with automated tests covering edge cases, unit boundary values, and regression checks.
  3. Content writing — Each tool page includes formula derivations, worked examples, usage scenarios, common mistakes, and cross-references to relevant standards.
  4. Peer review — Content is reviewed by practicing engineers familiar with the domain. We explicitly seek reviewers with hands-on experience in compressed air systems, pump sizing, HVAC design, and process engineering.
  5. Ongoing maintenance — Every page shows its last-review date. We revisit tools when standards are updated or when user feedback identifies gaps.

Standards We Reference

Our calculators draw on widely-adopted industry standards including, but not limited to:

  • ASHRAE 62.1, 90.1, 170 — ventilation, energy, healthcare
  • CAGI / ISO 1217 — compressed air performance
  • ANSI/HI 1.3, 9.6.1, 14.6 — pump standards
  • SMACNA — duct construction and testing
  • AMCA 210 — fan testing
  • API 610 — centrifugal pumps for petroleum
  • AHRI 550/590 — chiller performance
  • NIST SP 811 — SI unit usage

We cite specific standard numbers on each tool page so you can verify against the primary source.

Important Disclaimer

These calculators are engineering reference tools, not a substitute for professional judgment. All results should be verified against manufacturer data, applicable codes, and the review of a qualified engineer for your specific application. Conditions like gas composition, altitude, humidity, and equipment degradation can affect real-world outcomes beyond what a formula captures.

You should always consult a licensed professional engineer for critical designs, safety-related calculations, and code-compliance determinations.
