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.
