"J. Clarke" fired this volley in
in.local:

He hasn't "missed a bit". The "ton" rating is a well accepted industry
standard in the US.

I wasn't talking about the ton rating... he surmised the figures were
wrong because he didn't account for the additional heat absorption from
32F to 60F.

I know what a cooling "ton" is... I'll even bet Stormin' Morman knows.
G, but it only expresses a number of BTUs or calories absorbed per
hour... it does not calculate (or even intend to calculate) how many BTUs
are necessary to cool from one temperature to another. It's only purpose
is to give a unit name to how much heat it takes to melt one ton of ice
-- that means from 0C ice to 0C water; none other.
