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?
