    Yes plus fairly worthless because no one knows what they are swinging around.

    Oh well...off to the tool shop AGAIN.
    Being a 1959 model,I can switch between imperial and metric without even thinking about it.

    I have bought quite a few hammers over the past couple of months and reading this thread has made me realize (and I actually went out to the shed and checked) that every single one of them is Imperial.

    two ball pein hammers 32 oz and 40 oz, two 4 lb sledges and a 7lb sledge as well as a 3 lb club hammer. The 7 lb sledge and the Club hammer have the metric equivalent weight on them in fine print so I guess I can just use them if any metric jobs come up

    Welll this might be contentious then given the popular sentiment here. I'm equally at home using imperial or metric but for timber work I find imperial more user friendly for width and thickness (but not for length) - the graduations make more sense for the material IMHO. So I often play with things like 6x2 x 4.8.
    And I prefer my calipers to be reading in thou as well. Just plain easier on the eyeballs then all those decimal places.
    But I've tossed out both foot pounds and newton meters in favour of ugga duggas, which is the common mechanical standard worldwide nowadays.

    Not to be that guy...but you know thou ARE decimal places, right?

    not on my dial gauge calipers, which have become the preferred set because I can read it without my glasses still.

    Decimal feet were certainly used on river gauge boards pre-1974, but we also had feet & inches boards, for the gauge readers who couldn't understand the decimals.

    In advance of the conversion to metric, I did a large table with all the units we were likely to use in our organisation. After it was widely distributed, I discovered an error, so had to issue a correction.

    I moved on shortly afterwards, and when I returned to the organisation more than 10 years later, there were still copies of the erroneous table being used.
    I spent most of the 1974/75 summer drawing a metric plan using a decimal foot survey. The conversion factor (feet to metres) is etched into my brain .3048, .3048, .3048 ...

    and as late as 1989, I was still building stuff using imperial (decimal foot) plans. But by then you could again buy decimal foot tapes, so not really a biggie measurement wise.

    They're still decimal places, regardless of how they might be displayed

    About 20 years ago, I was involved in road and bridge construction for Florida DOT. There was, briefly, a directive to produce construction documents in metric. One bizarre effect was artificial precision: CAD programs had a default display of 4 decimal places; measurements were thus stated to the nearest 0.0001 mm.

    The whole thing fell out of bed because of land measurements. Right-of-way requirements were displayed in feet and hundredths, acres, etc. Reconciliation of the two measuring systems was considered too much trouble, and the metric program was abandoned.

    Cheers,
    Joe

    My computer comes up with 111mm but I know they didn't have computers 100 years ago so I'm not sure the computer has that right.

    This is so that I can make some custom inserts into a Rockler aluminium router insert that I bought from a dark remote isolated place in the world. So isolated dark and remote that it's the only place that is not metric. Yes I know it's impossible that such a place exists and yet it turns out it does. And no, as remote and isolated as it was, I didn't see any Yeti while I was there. Although there might have been some Neanderthals. I didn't hang around long enough to be sure.
    But that would explain the ancient measuring systems.

    I'm sorry if anyone was offended by my whinging. Just my warped sense of humour and a pet peeve of mine. Please don't take it personally, if you do happen like imperial.

    Good advise. Thanks mate.

    Only issue is that dear wife doesn't understand why I always need new tools for every project.
    From my point of view, its one of the best aspects of the hobby. Seems we have a disconnect here. However I can only push it so far, otherwise she'll explain that she needs new clothes for every outing. Which, of course, is just a plain silly waste of money and not the same thing at all but one has to pick one's battles.

    Dividers are only as good as your eyes and technique. I'll take numbers any day.

    The original metre distance equator to pole was dropped because from memory they mismeasured it. As Elan says then they went to standard bars as the metre definition. And here it is!

    the silver coloured bar in the middle was the original metre. The little cylinder was the kilogram and the bottle was the "cadil" which later got renamed to the litre.

    And it turns out that the inch has been defined in terms of the mm since metric was invented and all the US measuring system (including volume and temperature) is standardised on metric, but people just dont realise, as it is hidden behind their customary units.

    There was a rather excellent ABC podcast I heard on the radio around Christmas time.

    their units have to standardised on metric otherwise they would not be able to trade with the rest of the world.
