Spreadsheet program for engineering units? 5

[chrisjj]

Can anyone recommend a Windows spreadsheet program that understands engineering units?

E.g. will convert values automatically between units I have specified, and automatically display the units of the results of expressions of values in units e.g. energy (J) / mass (g) / temperature (J) -> specific heat (J/g/K).

Thanks.

Aibase is also a Windows program which can calculate with SI-unit expressions:

It's not a true spreadsheet program, because calculations are based on script, and version 3 has no functions to create large tables. It might be of interest though if not an office-like spreadsheet is required, but free-form documents with calculations.

I would recommend TechCalc100 found on Amazon.
It is a very practical Excel Technical Calculation Tool that requires no iteration, formulation, isolating variables, re-writing equations and replacing unknown variables.
