RF Cafe's spreadsheet-based engineering and
science calculator -
Espresso Engineering Workbook™ (click to download)
- is a collection of surface area and volume calculators for many geometric solids. RF Cafe
Espresso Engineering Workbook™ is
provided at no cost, compliments of my generous sponsors.

New in this version is a floating window that conveniently
lists all the worksheet pages. Just click on a page name to go there. There is a
button on the Home page to display all the bottom tabs with page names. Please
visit my advertisers to see what they can offer to support your projects.
All of the original calculators from years ago 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.
I been adding new calculators on a regular basis.
For the time being, the VBA code is 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.
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.
