Units of measurement
The WMF employs units and prefixes conforming with the Système Internationale (SI units). Including a short table of the acceptable units of measure at the front of the NF can encourage safe prescription-writing practices. Also remember to maintain the same safe practices when adding text to the NF, e.g. write microgram in full instead of µg or mcg, which may be misinterpreted as mg. In those countries where imperial measures are still widely used, it can be useful to include a conversion table for SI units.
