No. A Btu is a unit of energy, which has nothing to do with time.

Jargon is as jargon does, semantics aside.

Sadly, all too often, "BTU" is short for "BTU per hour".
When someone mentions a "24000 BTU" compressor, it is =understood= they mean
a 2-ton unit, or a pump designed for a system which moves 24000 BTU/hr of
heat.

In good humor at this point!!!

While at my local BJs Yesterday, they had 3 brands of window air
conditioners, all marked in BTU. No time unit on the boxes, *anyplace*. A
note, the sn sticker on the open display units did have BTU/h or BTU/hr
(both were used). But no mention of the nominal conditions at which the
labeled energy transfer rate is valid.

Just as the compressed gas industry uses cu-ft, much is implied. A 1 lb
steak should be in lbm to be accurate. Seems folks accept 1 lbf exerted on
a scale operated at 1 G as implied. After all, force was measured when
measuring the portion.

This irritates me no less less than our poor nickname for gasoline. We call
it "gas". It's pitiful.

What's worse, in general, one can't even buy gasoline. In general only
gasoline plus additives is available which is labeled "gasoline" ;-) So I
guess you meat "gasoline blend" and left out "blend" or "with additives"
VBG.

Of course, a check with yourDictionary.com yields: (#3 is of interest)

gas
n. pl. gas·es or gas·ses

diffuse readily, and the spontaneous tendency to become distributed
uniformly throughout any container. b. A substance in the gaseous state.

7. a. Flatulence. b. Flatus.

8. Slang Idle or boastful talk.

Language and it's usage is dynamic with time. And, I believe, even the
strictest scientist finds themselves implying some unit or parameter
needed for a truly accurate statement on a daily basis.
