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.
