Built for practical thermodynamics

From input values to useful insights.

A compact steam tables and thermodynamic property calculator for mechanical engineers, power engineers, technicians and students.

Thermodynamic calculations

Find water and steam states using pressure, temperature, enthalpy, entropy, saturation conditions and steam quality.

Interactive diagrams

Explore P–T, P–h, T–s and Mollier (h–s) diagrams. Zoom and pan to inspect selected states and thermodynamic regions.

Saved operating points

Save, rename, reorder and compare calculated states. Show or hide individual points directly in the diagrams.

See the real application

Engineering diagrams at your fingertips.

Visualize saturation boundaries, isolines, thermodynamic regions and your calculated points. These screenshots come from the Steam Diagrams Google Play listing.

Thermodynamic property reference

Know the state. Understand the process.

Steam Diagrams calculates water and steam properties with the IAPWS-IF97 formulation used in industrial thermodynamic calculations.

Choose supported input combinations, review results and display states in engineering diagrams. Configure units and select the isolines relevant to your work.
