Hi, In the process of extending math export I decided to finish and integrate an old experiment with units. Details can change as can configuration. \usemodule[dimensions] \setupbackend[export=yes] \starttext \startlines $10\su{km/h}$ $\su{10 km/h}$ \su{10 km/h} 10\su{km/h} 10 \su{km/h} $10 \su{km/h}$ 10 \su{KiloMeter/Hour} 10 \su{kilometer/hour} 10 \su{km/h} 10 \su{kilometer per hour} 10 \su{km / h} 10 \su{ km / h } 10 \su{km/ms2} 10 \su{meter per second} 10 \su{cubic meter} 10 \su{cubic meter per second} 10 \su{cubic meter / second} $10 \su{cubic meter / second}$ 30 \su{kilo pascal } 30 \su{kilo pascal square meter / second} 30 \su{kilo pascal square meter / kelvin second} \su{30 kilo pascal square meter / kelvin second} $30 \su{kilo pascal square meter / kelvin second }$ 30 \su{crap} 30 \su{AC} $ \frac{10 \su{m/s}}{20 \su{m/s}} $ {\ss 30 \su{kilo pascal square meter / second kelvin}} \stoplines \stoptext I might decide to push it in the core. The su is an abbreviation for scientific unit as we already have \unit (which I like more) and \dim is also taken. Of course \u would be even nicer but that's a accent placement (ok, we could drop all those as we have utf). Using two character names is not handy as they look like language switches.
