Hi!
I'm struggling with the rendering of a particular liquid metal:
%% renders as m (meter), not as Hg
\unit{mercury}
%% renders as mm·m, not as mmHg
\unit{millimetermercury}
This is strange, since both “mercury” and “millimetermercury” are
defined in phys-dim.lua. To get mercury recognised as a unit this
can be used:
\registerunitshortcut [mercury=mercury]
Now \unit{mercury} renders correctly as Hg.
Why is that \registerunitshortcut necessary? Is it even correct to
use it like this? However, even then millimetermercury doesn't
render correctly:
%% renders as mm·Hg, not as mmHg
\unit{millimetermercury}
How to get millimetermercury render as mmHg? And “inch mercury”
render as inHg? I can't find “inchmercury” in phys-dim.lua, only
“millimetermercury”, should it be added?
Example:
%% \enabletrackers [physics.units]
%% inch should render as “in”
%% \setupunittext [inch=in]
\starttext
\unit{mercury}\crlf %% renders: mm · m
\unit{12 millimetermercury}\crlf %% renders: mm · m
\unit{12 inchmercury}\crlf %% renders: in · m
%% why is this necessary to get mercury rendered as Hg?
\registerunitshortcut [mercury=mercury]
\unit{12 millimetermercury}\crlf %% renders: mm · Hg
\unit{12 inch mercury}\crlf %% renders: in · Hg
\stoptext
Questions:
1) Why is \unit{mercury} not working, although it's listed in
phys-dim.lua?
2) Is the call \registerunitshortcut [mercury=mercury]
necessary/correct?
3) How to make \unit{millimetermercury} render as mmHg and
\unit{inch mercury} render as inHg?
Marco

None of your examples work because millimetermercury and mercury are the
names for the labels
and the units are accessed with hg and mmhg.
\setupunittext[en][millimetermercury=inHg]
\starttext
\unit{mmhg}
\stoptext
