Unit Converter For Engineers vs convertX

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.
