I'm sure she meant to write kgf. BTW did you assume 9.81m/s^2 or
Actaully, this was a qurstion on a job application form. Quite what the
relevance of my weight is to my abilities as an electronic designer is
totally beyond me, so I deceided to 'have some fun'.... No I didn't get
the job, but after seeing the organisation i wouldn't have wanted it anyway.
did you account for local gravitational field strength
variations :-)
The former... Mind you _they_ didn't speicify the place where they wanted
me ot measure my weight, so I think taking a nominal value for g is
justified...
And it's
one of the most stupid laws we have! Provided both parties
involved in the transaction agree on what is being traded,
the governemnt
should not interfere. If I want to buy 5 yards of cable, and
the shop is
prepared to cut me that length, what is the problem?
The problem is that some smart Alec will sell you 5 Elbonian
yards (but the Elbonian part will be in really small print, in
white ink on a white background). Weights and measures have been
regulated in various ways, in various places for a long time.
The only thing that's changed recently is the units that can
be used. A free-for-all will just let the con merchants thrive
But that is a problem whatever units are used. I could sell you 5 metres
of cable and claim I was using a 'metre' other than the standard one. No
I don't think I'd get away with it, just as I don't think that you'd get
away with using some odd 'yard'.
I think you should be able to use any units you like provided they have
an accepted definition (all the imperial units do).
And if I ever have to ask for a 6.35mm tap, 1.27mm pitch, 0.96 radian
thread angle (as against a 1/4 inch BSW tap) I will go insane!
