Hi Ros,
Many thanks - that's pretty clear.
I agree about the CF documentation - "udunits.dat" peppered all over the
place.
We'll use a unit of '1' instead (our application needs each variable to
have a unit, even if CF doesn't!).
Best Regards,
Ian.

Hi Ian,
The CF Checker using UDUNITS-2 to validate the units.
This is another one of those units where UDUNITS-1 deemed it valid and
UDUNITS-2 says it's invalid.
I think the CF Document should be updated to specify validation against
UDUNITS-2 and also to remove the reference to the udunits.dat file as
this no longer exists at UDUNITS-2, instead xml files are used.
Regards,
Ros.

Sorry, didn't quite finish.
... it says:
ERROR (3.1): Invalid units: bits
So: is "bits" (or "bit") CF-compliant or not?
Thanks for any help,
Ian.

Hello,
The latest CF-compliance document suggests that we should look
to the udunits.dat file in the udunits package to find out if a certain
unit is CF-compliant. The latest version of udunits.dat I have lists
bit P count
as an acceptable unit. Yet when I run a file with this unit
through the CF-compliance checker, it says:
