## What is Thermodynamics Calculator?

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.

### 1/5 — App simples e básico!

*2025-03-28*

Não gostei! Achei o app muito simples e básico. Não converte e nem calcula tudo que promete, Ex.: as leis da termodinâmica aparecem apenas como conceitos, achei enganoso.

**Developer response:** Lamentamos que você não esteja satisfeito com o aplicativo. Tentaremos melhorar na próxima atualização. Entre em contato conosco pelo e-mail contact.pugal.apps@gmail.com.

### 4/5 — Text description

*2023-06-14*

Very nice app. I could not figure out to display the full text.

### 1/5 — Absolut nutzlos!!!

*2023-04-26*

Vieles auf englisch. 
Formeln lassen sich nich umstellen oder nach gegebenen Werten rechnen lassen. Grundformeln sind allen bekannt. Schade um das Geld.

### 5/5 — Rams30

*2012-08-29*

Great App..I find it really useful for my engineering..covers almost all calculations in thermal.. must be useful for engineers and students .. u get formula and is easy to use.) good work!..
