The free calculators that come with Windows?

My keyboard has 2 separate buttons that each bring up "Calculator", one on
the main keyboard and the other on the detached cordless keypad.

You can also get "Microsoft Math" or similar if you want something to do
equations. But seems the built-in current Windows 10 Calculator has
"scientific" and "graphing" calculators, so apparently it can handle
equations.

But let me guess... You require it for a specific older version of Windows...

Track down a PIRE Wheel. That is all you need.

An often used trick is to print triangles like:

P
-----
U * I

or:

U
-----
I * R

Then, to calculate something (e.g. P), cover the wanted result (P)
and read the remaining terms: U * I to know how to calculate it.

Search for "Ohm's Law Calculator". Most include Power. For example:

<https://www.microsoft.com/en-us/p/ohms-law-calculator/9pcp2b4q6sc5>
<https://safeforpc.com/ohms-law-calculator-for-pc-windows-and-mac-free-download>
<https://napkforpc.com/apk/com.mkvsoft.ohmslawcalculator/>
etc...

I'd move on rather than spending time with that type of an employer.

I tried the 1st couple of suggestions. I didn't like how all fields had
to be reeset to get a fresh calculation. Am reminded of a simple program
I wrote years ago (free on request) to check two dates and the period
between. Three fields of which two track each other if the 3rd is marked
as fixed. Maybe V, A, R & W could be treated the same way.

Since you 'simple program I wrote years ago'....create a spreadsheet. Simple enough
Don't have Excel? Dnld and install LibreOffice
https://www.libreoffice.org/
just install the spreadsheet app

Well, since you're not the OP and seem to have some additional
requirements, perhaps it would be best to write your own program or

This one looks like a good start:

Yep. Check 2 boxes and inscribe the values and it calculates the
missing two values. To make it run standalone and without internet,
copy the libraries specified in the header to your local machine,
tweak the code, and run it from a web browser.

Note: I are not a programmist.

Convert anything.

Allows user-designated unit conversions to be added. . . .
