Correct abbreviations

Correct abbreviations

(OP)
Hi
I need some HELP for the correct way to abbreviate a torque rating.
For years I've called it out this way: i.e. 125,000 lb in @ 3,000 psi.
NOW I'm being told to call it out this way: 125,000 IN*LBF @ 3,000 PSI.
Which way is correct? My understanding is #1 that it should always be
lowercase and #2 to use the ANSI/ASME Standard when in doubt. As far
as I can tell the standard says to use "lbf*in" or "lb in" and "psi"

I've used this rule for 40 years. No I'm told I am wrong.
Thanks

RE: Correct abbreviations

Torque and work are Force X Distance so the units should be LB-IN.

Tunalover

RE: Correct abbreviations

It should be slug * acres/ft.

Or whatever other units seem to work for the circumstance. If it were easy, we wouldn't be talking about it, and a one size fits all mentality won't work.

Take a look at the thread below for some other perspecives.

RE: Correct abbreviations

Tunalover, Then, multiplication being associative, what's distance x force.

I hate Windowz 8!!!!
