Units

< Math | Sciences | Dimensions >

Use the built-in \unit command to parse units. Some examples of this are shown below:

10 \unit{km/h}
\unit{10 km/h}
\unit{~1 km/h}
\unit{KiloMeter/Hour}
\unit{10 cubic meter / second}
\unit{kilo pascal square meter / second}
\unit{kilo pascal square meter / kelvin second }$
\unit{10 AC}
$\frac{10 \unit{m/s}}{20 \unit{m/s}}$
{\ss 30 \unit{kilo pascal square meter / second kelvin}}
\unit{123.22^-3 km/s}
\unit{123.22e-3 km/s}

ConTeXt will take care of spacing and formatting. The parser is fairly flexible, and the following all work and give the same output.

\unit{10 kg} \unit{10kg} \unit{10 kilo gram} \unit{10 kilogram} \unit{10 Kilo Gram} \unit{10 KiloGram}

The command works in text as well as in math mode and spaces are normally ignored. You can define your own command:

\defineunits[un][alternative=text,separator=medium]

Valid separators are cdot, big, medium, and space with the first being the default. You can later tune the rendering with

\setupunits[un][separator=cdot]

Numbers are formatted cf the \digits mechanism (not discussed here).

Additional documentation is available in the Units manual.
