Yes I see that. But it also says 'Their use is not encouraged'.
The BIPM bible states:
"4.1 *Units used with the SI*
The CIPM (1969), recognizing that users would wish to employ the
SI with units which are not part of it but are important and widely
used, listed three categories of non-SI units: units to be maintained;
to be tolerated temporarily; and to be avoided.
...............................................................................
"Table 8 lists some other non-SI units which are currently
accepted for use with the SI to satisfy the needs of commercial, legal
and specialized scientific interests. These units should be
defined in relation to the SI in every document in which they are
used. Their use is not encouraged."
Table 8 lists nautical mile, knot, are, hectare, bar,
�ngstr�m, and barn.
