Thermodynamics Calculator puts 44 thermodynamics and heat-transfer calculators — plus a library of thermal engineering reference tables — in one fast, offline app for engineers and students. Sizing a heat exchanger, checking a Carnot efficiency, or looking up the emissivity of a material? You get the formula, the result, and the reference data in seconds. WHY ENGINEERS USE IT • Solve for any variable — on most calculators, rearrange the formula and solve for whichever value you're missing, not just the "standard" output. • SI and USCS (Imperial) units — switch the whole app between metric and imperial with one tap; every input, result, and unit label updates instantly. • Reference tables built in — emissivity coefficients, thermal conductivity of common liquids and heat-exchanger materials, radiation constants, and more. • Find it fast — search plus category filters: Heat Transfer, Thermal Expansion, Radiation, Energy & Work, Dimensionless Numbers, Properties & Tables. WHO IT'S FOR Mechanical, chemical, and HVAC engineers, and thermodynamics / heat-transfer students who want quick, reliable answers without digging through a textbook.
