Important: The "runtime-files" folder must be extracted from
the ZIP file along with the main XLSM spreadsheet file.

The first major new release of RF Cafe's spreadsheet (Excel) based engineering
and science calculator is now available -
Espresso Engineering Workbook™ (click to download).
Since 2002, the original Calculator Workbook has been available as a free download.
Continuing the tradition, RF Cafe Espresso Engineering Workbook™
is also provided at no cost,
compliments of my generous sponsors.
The original calculators are included, but with a vastly expanded and improved
user interface. Error-trapped user input cells help prevent entry of invalid values.
An extensive use of Visual Basic for Applications (VBA*)
functions now do most of the heavy lifting with calculations, and facilitates a
wide user-selectable choice of units for voltage, frequency, speed, temperature,
power, wavelength, weight, etc. In fact, a full page of units conversion calculators
is included. A particularly handy feature is the ability to specify the the number
of significant digits to display. Drop-down menus are provided for convenience.
Now that a more expandable basis has been created, I plan to add new calculators
on a regular basis.
For the time being, the worksheets and VBA code are password protected. At some
point, a version might be made available with full access, but during the development
stage, I prefer to not expose all my hard work for easy poaching.
Note that the ZIP file includes both the XLSM spreadsheet file and a folder named
"runtime-files." The folder is required for the spreadsheet to run.
A lot of effort has been expended validating calculations, including references
from books, magazines, and other software. As always, you are advised to check results
against other sources if something seems off. If you do find an error, please report
it to me ASAP so it can be corrected with the next release.
The file is in an xlsx format compatible back to Excel 2007 - and it
may work for even earlier versions.
* Note: Because VBA code is used, you must allow Excel security
to enable macros.
