I have been in the aviation industry specialising in Logistics all my life. There used to be a standard, the ATA 200, for how to abbreviate the unit of measures, such a EA for each, KG for kilograms, HU for hundred, and so on. I understand that the ATA 200 is now dead and has been replaced by ATA Spec 2000 but I can not find these abbreviations in the Spec 2000.
I suppose that these abbreviations are still valid but where can I find them?
