Torque seems to be quoted in Nm instead of ft-lb these days.
I am finding I need to get calculator out (Nm x 0.738) to convert to ft-lb to compare.

When did it suddenly shift to this as it's really annoying that I have to work it out biggrin

Along with metric, Nm is the international standard. Most torque wrenches I use these days have Nm and Kg/m/s something, somthing... I just stick to Nm.

I usually just ask google and it provides the answer.

Agreed. In the sixth form we used metric units from 1964 to 1966, we had one year in uni before we changed from imperial to SI units (From 1969, Examinations for students starting higher education courses in science, engineering or technology are set in SI units). At work (automotive industry) we used SI units since I started in 1970.
Torque should be in Nm, and power in kW.
Multiply by 1.36 to get from lbf.ft to Nm.
Multiply by 0.75 to get from bhp to kW

Hopefully miles is next. But if the likes of Jacob Rees Mogg has his way, we'll be going back to buying things measured in lbs. Presumably he wants to bring back pounds, shillings and pence too. And the black death too.

Ah, miles, the good old Roman military measure. A mile was ‘Mille passus’ , a thousand paces. These were of course ‘double paces’ that is each time the left foot came down was a pace.

Imperial is going nowhere whilst the USA is the hegemony.

Apart from the fact that it's err, quite obviously been going away for the last 60 years and just holding on in a handful of areas but even going from those as this thread kind of illustrates? But, yeah, it's absolutely not going anywhere and it's all down to the crushing dominance of the USA.

You can quite literally Google the answer.

My 50yo Williams talking wrench has ft/lb and kg/something scales. I still use ft/lb as well.

Bring back proper imperial measurements, non of this EU rubbish is wanted here!

John Wilkins proposed the metric system in 1668. Before the EU, before the US, before Napoleon and before Mouton.

It's an English system. We just offshored the labour and then no one remembered to tell Merica. biggrin

When do you anticipate the USA will stop using imperial measurements?

UK is always going to use a mixture of both.

I'm another one who is so used to Ib-ft that I don't have a clue what NM is in comparison. I do like some of the YouTube videos that quote both figures though and that helps me.

To all of those desperate to return to 70s standards, you should be able to do the mental maths very easily if you passed your O-levels.

Nm to lbft? Divide by 4, multiply by 3.
The inverse? Well, that's the inverse.

Happy to help.

As we can see, the US remaining in Imperial hasn't stopped other markets moving away so their hegemony is proven not that relevant in this regard.

And we can all see that the U.K. uses a mixture of both and so what we are actually considering is the steady shift of the balance of that mixture which has been moving very steadily and clear for all to see for the last 60 years. Wholly regardless of US economic, military and even cultural might.

I'd hazard that after GenX there will just be a few legacy Imperial measurements remaining in common British parlance, maybe the pint and mile will survive?

The engineering and science community in the USA use SI units in my experience in design. Component drawings, and test procedures were always in SI units. They were international documents, and thus used by suppliers and engineers worldwide.

I worked for a US OEM for 11 years. Everything was in metric, or more correctly SI.

I don’t think I’ve worked in anything other than SI units in my professional life (20yrs). One exception being a steel mill which was originally designed as imperial so you had to convert, resulting in some very odd measurements.

At home used to be different, what with miles and lb ft and so on. Only I’ve not lived in uk for 12yrs now so thinking in km, liters per km, nm and the rest is my default setting.
