Dear Barry,
Thanks for posting the web address for the draft 9th SI.
I have long been concerned about the use of the word
quantity in SI. To me quantity means amount. I think the public
also thinks quantity means amount, that is, how much. In the
draft, including the history part, I find no text saying why
this word quantity is used. So, who can tell me?
I propose that quantity be deleted and the word property
be used instead. There might be another English word to use.
Somebody tell me what to use.
Property is what units are about.
"Property" is used throughout the text so this change is
not easy but let's do it. We have confused the public too long.
