Now, how about being magnanimous for once by admitting that you got something wrong?

My experience.



Torque as expressed in vehicle maintenance

imperial: pound feet abbreviation lbf or lbft.
Metric : newton metres abbreviation Nm


SI torque units are measured in Joules (J) (not equal to Nm!).

It's pounds force feet (lbf.ft) if you want to be absolutely correct. 'Google' "Imperial units of torque" and you'll see.

Thanks Simon.

that just answered my question (genuinely asked) earlier. It is NOT weight, but MASS.

lbf.ft is Not something I've seen written in any automotive workshop manual.



I did carry out an admittedly superficial web-search for torque units.
If you'd really like to 'Google' to see which is most popular in use.
The most popular in Google Books is...
...
... wait for it...


lb/ft


Interestingly lbf.ft isn't even found....


But here's the ngram itself...


Try it for yourself - Heres the link - torque ngram




Besides: my point is that it's just nit-picking to argue between
lbf or lb/ft or lb.ft or lbf.ft It doesn't really make any practical difference - Unless you are going to use the SI torque unit of Joules.



My torque wrench is calibrated in Nm anyway.



I'd rather discuss the best ways to use a torque wrench than argue over the above.

Maybe, but, in engineering circles, it is commonly referred to as lb.ft, without the "f".
Interestingly, a torque wrench that I bought, when I was a an apprentice mechanical engineer, is marked as such.
(That was through weekly instalments to the "tool club", as tools were expensive, in relation to earnings, back then).

"Pounds Foot" was a pretty straight forward description, as the extra "f" would have made it cumbersome to say.

In fact, normally, when I was on the shop floor,, it was important to reserve the extra "f"s to describe the job in hand and some extra "f"s to conclude the outcome.

Something I wonder, ever since being told off by my physics teacher 30+ years ago. I imagine for calibration it would be relevant.

Only relevant if not subject to normal earth gravity. ....

I'm afraid the last sentence will confuse Simon no end Bob, it may as well be written in a foreign language

Anyway, I noted this evening while torquing up the various fasteners disturbed in the overhaul of the ZT, that the Norbar 1/2" drive torque wrench is marked up in Nm and lb/ft and the 3/8" Britool one marked Nm and Lbf.ft how about that

It's a shame because no one really cares, what matters is whether or not you make yourself understood, and I'd prefer to take my advice from an old hand, than a pedant with a shiny seat on their trousers

thanks for that Avulon. The link within my last post explained what I was wondering, with a clue from a suggested search in one of Simon's posts. With all the pedantry that was being discussed, I thought it was a good chance to ask lol. Being pedantic about it, would I be correct in thinking that it is mass, since earth's gravity would not be applying the force, but the mass being applied by the operator (ie you when you when you turn the wrench)?

the mass/weight thing was always something that stuck in my mind from school.
