Liquid Properties Calculator — online
543 chemicals in one alphabetical list, or a liquid mixture: density, cp, viscosity, conductivity, surface tension, vapour pressure, latent heat, heating values and hazard data at any T and P.
Yellow cells are inputs; orange cells are choices; blue cells choose the unit. Select or hover over an input to see its help in the box below the toolbar. The sheet is the same as the Excel tool (USD 49) — the Guide, method and references are in the Excel file.
What this liquid properties calculator does
Pick a liquid or a blend, enter T and P, and every property appears. 543 chemicals in one alphabetical list, or a liquid mixture: density, cp, viscosity, conductivity, surface tension, vapour pressure, latent heat, heating values and hazard data at any T and P.
- 543 chemicals, A to Z. The same library as the Gas Properties Calculator, with liquid property curves for each chemical.
- Pressure corrections. Compressed-liquid density, and pressure corrections for viscosity and thermal conductivity.
- All the liquid properties. Density, cp, viscosity, thermal conductivity, surface tension, vapour pressure, latent heat, expansion and compressibility.
- Liquid mixtures. Ideal-solution mixing rules, bubble point and mixture flash point.
- Your own data. Enter a measured density or viscosity and the tool corrects the curve through your point.
- Heating values and hazards. HHV and LHV of the liquid, NFPA 704 ratings, GHS statements and flash point.

Questions
Is the liquid properties calculator free?
You can enter and check all your data free. The full results, findings and printable sheet are unlocked with a 3-run pack (USD 9), a monthly subscription to all 40 online tools (USD 15) or a yearly one (USD 99).
Are the results the same as the Excel tool?
Yes. The online tool runs the formulas of the Liquid Properties Calculator Excel workbook, checked cell by cell against the Excel file.
Which units can I use?
SI, US customary and British units — choose the unit next to each input.
