Prefixes on non-SI units when commonly used in certain industries

Reported by: brunogirin Owned by:

The standard currently specifies that only SI units can take prefixes. However, there are instances where prefixes are used with non-SI units in particular industries. For instance, the retail gas industry in the United Kingdom often install gas meters that measure consumption in hecto-cubic-feet.

Should there be a way to describe industry specific exceptions to the above rule? (possibly with caveats that such units should be used carefully)
