This is the third post in a series. The author (Jason Scott) is trying to save ~25,000 manuals, instruction booklets, and engineering notes (largely electronics related, created over the last 80 years). This is a large project, the company which owns the manuals currently is going out of business, and all the manuals will be thrown away very soon (re: tomorrow).
It is infeasible (IMHO) to deal with all physical manuals ever in this way, unless you are literally a Manuals Library that is supported by the county or whatever.
I think the only way to go forward is to digitize the shit out of everything.
"On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."

" Admittedly, I'm not entirely sure why being a non-linear transform gets the OP so riled up."
Because it's harder to calculate mentally
One can approximate 2lb to 1kg roughly, 1mi ~ 1.6km, but for Fahrenheit this is harder
One solution is to establish a set point ( 70F = 21.1C, approximate to 20C ) then work in differences, since 1.8deltaF = 1deltaC so, 2dF ~ 1dC (or 10dF ~ 5dC)
Hence, 90F is approximately 30C (exact value, 32.2C)
