I posted their metric practice guide in another post. It is hard to tell exactly what they use as most of their conversions are highly rounded (3 or 4 figures). They clearly use the International foot and inch (everybody does except surveyors), they use a rounded pound (0.4536 kg), not the same pound every other inch-pound organization uses.
They oddly use the International Table BTU and the thermochemical calorie. I would expect any organization to prefer one or the other so the units are related by the degree size and lb/kg relationship. An organization affiliated with ANSI HAS to have a metric policy. My opinion is that they passed just enough of one to get ANSI off their backs. For an organization actually trying to metricate, I consider it an inadequate policy (and practice). It will not lead to rapid metrication (it may NEVER get there). ________________________________ From: Pat Naughtin <pat.naugh...@metricationmatters.com> To: U.S. Metric Association <usma@colostate.edu> Sent: Mon, January 10, 2011 4:56:47 PM Subject: [USMA:49467] Re: Btu Dear Robert, Thanks for the list. Are all the old measuring words used by ASHRAE really metric measuring words in disguise. For example, I think it is likely that, for the first three, they are using: the metric foot of 1959; the metric inch of 1959; the metric square footage of 1959? After that I am in doubt. Is the "R value" really a metric value? I the metric kBtu really a simple multiple of a kilojoule? And so on for the rest. Cheers, Pat Naughtin Geelong, Australia On 2011/01/11, at 08:30 , Robert H.
