Hello Jim et al I have followed your path and I agree with your analysis
It looks like my assumption, and a whole part of my discussion thread, is based on a piece of code in a third party udunits wrapper which is not part of udunits. Hence I have been muddying the issue with an interpretation which is not valid. Apologies for the confusion this has caused. I now retract all my statements linked to units = '' as udunits unequivocally interprets this as equivalent to units = '1' I will consider this some more and try to come up with a coherent thought process which is supported by the software. all the best mark ________________________________________ From: CF-metadata [[email protected]] on behalf of Jim Biard [[email protected]] Sent: 06 November 2014 20:15 To: [email protected] Subject: Re: [CF-metadata] string valued coordinates Hi. Just out of curiosity, I used udunits-2 to do a test to compare units of '', '1', and 'kg/kg'. They all evaluated as equal to one another.
