Hi, most of these issues already have been discussed last year¹, but they don't seem to be solved, yet. 1) \unit{10^3} does display as 10✕10³. This is confusing and wrong. 2) Expressions like \unit{e3} result in ✕10³ instead of 10³. The multiplication sign should be dropped in this case. 3) The minus sign: \unit{e-3} It's too long. In math mode the correct character is used, but the spacing is messed up. 4) AFAIK there's not yet an interface to change the multiplication sign. \def\digitstimessymbol {\kern.2\emwidth\cdot\kern.2\emwidth} Full example: \starttext \unit{10^3 second} \crlf %% ⇒ 10✕10³ s \unit{10^{-3} second} \crlf %% wrong — sign, too long \math{\unit{10^{-3} second}} \crlf %% wrong spacing \unit{e3 second} \crlf %% ⇒ ✕10³ s \stoptext Marco ¹ http://www.ntg.nl/pipermail/ntg-context/2012/070057.html
