Finally…a spreadsheet designed for science and engineering. See here for an example of how the DimensionEngine Excel add-ins simplify science and engineering calculations while reducing errors.
DimensionEngine - The DimensionEngine Add-In for Excel is much more than a units converter. DimensionEngine analyzes spreadsheet formulas, automatically converting units as necessary, outputting formula results and their units, and indicating when inconsistencies are present so that errors can be identified and corrected. Fewer errors. Less work. All with just one click. (Windows and Mac)
