I don't know everyone's use of \units but for physicists I think that the only
case where it should be usefull is for 10^something (like \unit{10^-12 second}
;). Maybe the informaticians need 2^something… The other cases are probably
marginals.

That's already working and this should be the way when one need something
unusual. Maybe a support for \m{} should be usefull for those who do not use
$...$ anymore. For the moment nested curly brackets aren't supported inside a
\m{} which himself is inside a \unit{}.
All the best.

Wiki: adapted. (Page created, actually, as there was none.) Using the
fancy-schmancy {{since|2012|text=nov 2012}} template, which (1) marks
this as a recent feature, and as such not in the stable yet, and
(2) sticks it in the hidden categories [Since] and [Since 2012], so
that we may review (and remove) those tags when the new stable comes
out next year.

Nobody seems very enthusiastic concerning this thread so I tried to go further
in the comprehension of the phys-dim.lua code. I now have found an approximate
solution to my problem :
\unit{$10^{-12}$ second}
give the right result. It is not very satisfactory because I'm now used to use
\m{} instead of $ $. In the phys-dim.lua code, the line 64 shows that \m{} can
be used inside \unit{} but this doesn't work for:
\unit{\m{10^{-12}} second}
because the pattern doesn't handle nested curly braces.
Is there any Lua expert to find a pattern to handle exponents?
Thank you.

I'm not an expert neither in TeX nor Lua, but I quickly glance at the source
code (phys-dim.*) and here is what I understand:
— the brackets { } are not recognized (a comment in the lua code mentioned
it), so \unit{10^{-12} second} should be \unit{10^-12 second};
— the hat sign '^' is recognized as 'e' so it means "… times ten to the
power…" instead of "to the power…" as one should expect.
So I come back to my problem. I want to write 10⁻¹² s (ten to the negative
twelfth power second). Actually, I'm typing \math{10^{-12} \unit{second}} but
I'd prefer to type \unit{10^-12 second} (for coherence). Is it possible to
modify phys-dim.lua in that way or is this to much work (I have no idea if
this is a matter of changing one line or a hundred lines in phys-dim.lua.
Maybe also this is a too specific request, I don't know…
Anyway, thank you in advance.
All the best.

[NTG-context] \unit problem with powers of ten.

I got some problems to express powers of ten in the \unit command. See the
strange behaviour with these two minimal examples.
\starttext
\unit{10^2 meter}\\
\unit{10^{-12} second}

However, there is no problem with this one: \unit{1e-4 kilogram}.
Is this a bug or are these expressions not supported?
