I have thought of designing and making a stringed instrument. So I went online
and found www.juststrings.com, which sells strings for various instruments
and strings in various sizes. AFAICT their thicknesses and lengths are all in
inches. Does anyone make strings in micrometers?

I've been reading the statics book. It consistently uses °C for temperatures
and C° for temperature differences. Last time I looked at the set of SI
symbols, both temperatures and temperature differences are designated by °C.
Was C° official, and when was it in use?

I didn't know doctors were still prescribing in IUs (see article below).
An excellent reason (as Paul has pointed out in the past) for
standardizing on SI.
The IUs (they are substance-specific units, so plural) are used for chemicals

The paper sizes used for maps in North Carolina are defined by GS 47-30 as the
following:

21 in × 30 in (533 mm × 762 mm)
24 in × 36 in (610 mm × 914 mm).
None of these is close to an A or B size. 914
