Using Farad with \unit messes up feet, µ not recognised as prefix
Hi! I struggle using the unit Farad (unit of capacitance): \starttext %% prints 10 10 ft \unit{10 F} \unit{20 ft} \registerunit [F=Farad] \setupunittext [Farad=F] %% prints 10 F 20 F⋅t \unit{10 F} \unit{20 ft} \stoptext When registering Farad as new unit it messes up feet. This looks like a bug to me, since “20 ft” does not contain a capital “F” and units are case-sensitive. How to use Farad correctly without messing up other units? 2nd issue: The prefix “µ” is not recognised: \starttext %% prints 10 nm 20 30 µm \unit{10 nm} \unit{20 µm} \unit{30 um} \stoptext I would expect “20 µm” to produce the correct result. Can we make “µm” also produce the same result as “um”? Marco LMTX 2023.09.04 19:15

Hi!

The unit "farad" exists.
\starttext
%% prints 10 10 ft \unit{10 F} \unit{20 ft}
\registerunit [F=Farad] \setupunittext [Farad=F]
%% prints 10 F 20 F⋅t \unit{10 F} \unit{20 ft}
\stoptext

The unit for feet is "foot" and "ft" is a combination of a prefix (femto) and a unit (tonne). You can list the individual parts in the log file with the "physics.units" tracker. To get a short unit you have to use the following method (it works because farad exists): \registerunitshortcut [F=farad] Wolfgang

You're right \unit{10 Farad} works.

Makes sense if you think about it. Never crossed my mind that ft not meaning feet in this instance and also never contemplated the existence of a “femto tonne”.

That gives some insight, indeed. Thanks. What about: \unit{10 um} \unit{10 µm} Can I assign µ to mean micro (prefix)? Marco

Found it: \registerunit [prefix] [µ=micro] \starttext \unit{10 micro meter} \crlf \unit{10 µm} \stoptext Should this be the default (µ assigned to micro)? Marco
