There's
really no excuse for such nonsense. I see people using "Watts" do describe
energy, not power also. that doesn't make it correct.
Or ?pounds? for mass. Or ?kilograms? for force. :-)
At one time it was quite common to see torques given in kg.m (which is
,of course, nonsense). More recently manuals quote torque settigns in
daN.m . THing is, of course, that a daN.m is very close to a kgf.m (the
approxiamtion being that 'g'=10), so you can use your old torque wrench
calibrated in kg.m with the same numbers. For many applications the exact
torque when tighenting a bolt is not tht important. What is important is
that (a) it's tight enough to hold the <whatever>, (b) it's not so tigth
as to strip the trhead and (c) that all the bolts holding something on --
let's say tghe cylinder head of an engine -- are done up to the same
torque so that the thing is held down evenly.
I was one asked for my 'weight' on a job applciation form.Quite what
relevance that has to being an electornic engineer is beyod me, but...
The form had a space to fill i nthe numebr iwth the units 'kg' given. I
crossed otu the 'kg' and wrote 'N'. And gave the appropriae value. I
never head from them again...
