I never thought of using the full word 'gram' - I've just checked and
'gram' and 'mgram' work on udunits-2 as well. Thanks.

However, I'm still concerned that there are differences between the 2
versions, and that this should be at least noted in the conventions.
Other people in the future will probably have the same problem, and it
would be nice to have a definitive answer. My (strong) personal
preference is to say that all unit strings should be correct when
interpreted with udunits-2, rather than relying on a set of 'hacks' to
ensure compatibility between the 2.

Cheers,
Andrew
