Unit Converter For Engineers

Includes engineering charts, An Advanced Engineering calculator, tools, and rare units most converters don’t have — works 100% offline.

Built for engineers who work with units most converters don’t have. No ads. No popups. No distractions.

If you’ve ever opened PDFs, charts, or old handbooks to convert Rockwell hardness, wire gauge, HVAC airflow, radiation dose, water hardness, or torque units — this app replaces all of that.

Units you usually can’t find in converter apps

Material Hardness Rockwell (HRC, HRB, HRA), Vickers, Brinell, Knoop, Mohs, Shore

Wire Gauge AWG, SWG, MCM, kcmil, diameter, cross-sectional area

HVAC & Airflow CFM, ACH, BTU/h, tons of cooling, kW, airflow per area and per person

Water Quality & Chemistry ppm, mg/L as CaCO₃, grains per gallon (US/UK), °dH, °fH, dKH, mmol/L, meq/L

Radiation & Radioactivity Becquerel, Curie, Gray, rad

Mechanical & Structural Torque, stress, density, pressure, moment of inertia (kg·m² ↔ slug·ft²)

Built for real work environments

• Works 100% offline in labs, plants, and job sites • Fast search and instant conversion • Scientific notation for precision work • Fraction input mode for field and construction use • Clean, engineer-friendly interface — no ads, ever

This app replaces reference charts, calculators, handbooks, and repeated Google searches with one reliable tool in your pocket.
