    Metric or imperial? Which system should rule the world?

    1. Metric is magnificent

      23.3%
    2. Imperial is incredible

      76.7%

      I'm from the US, and so am comfortable with the imperial system....but the math is indisputably easier in the metric system. The only part I have difficulty with in the metric system is when I have to estimate a size that would be bigger than three inches, and smaller than half a meter. The foot and inch come in handy in these instances because they seem more "human" estimates. For instance 25 decimeters....I have a hard time guessing it...but as I said, I grew up using the imperial system. Also, what happens when you need something smaller than a millimeter? I don't know the unit. I wish they had taught us more in school about it.

      the unit system is up to the habit by the industry.I prefer metric. it seems normal coz human has 10 finger, easier to be used for counting and calculation.

      I voted for "imperial" just to be a curmudgeon (and because that's what I use 99% of the time), but logically I realize that metric is superior. Where I work, all of our product drawings are in metric with dual inch dimensions given, but all of our machinery (which we build in house) is in inch, with inch hardware.

      When I can order steel and aluminum in metric sizes from the local supplier here in the US I'll switch to metric... but for now raw materials are only easily available in 1/16, 1/8, 1/4, 1/2, etc...

      Then there's sheet metal in gauge thicknesses... compared to that, inch units are perfectly logical!

      Here's a question for engineers in all-metric countries... what are the standard available thicknesses and widths for small bar stock (e.g. 1-50mm)?

      Personally I'm comfortable with both.

      Educated at home in imperial and educated in school in metric.

      I used to think in imperial and convert to metric in my head. Nowadays I tend to do it the other way around

      I voted imperial as it was looking pretty lonley :)

      As much as I hate metric things like KM's, at least metric is logical whereby everything is factors of ten. I haven't met an American yet who knows what temperature water freezes at, obvious in Metric though, the scale is 0-100 so it's easier to have an understanding of what happens in between.

      It is rather strange in the UK how we buy apples in lbs if they're loose, but KGs if they're bagged. Liquids in mls, unless it's beer/cider, in which case it's pints. But we still measure spirits in mls.
      We measure small things in mms but large things in miles. The only people who use kMs, are people who are obsessed with running, because it sounds like they ran further if they quote it that way.
      Feet get a mention, but no-one actually knows what one looks like unless you were born before the 80s. The only thing anyone seems to measure in inches is the size of the male genitalia.

      I have been metric for so long that my ability to judge distances, long or short, has severely waned. Metric is sssooooo much easier. I worked as a consultant in the semiconductor industry for a few years and was astonished to learn that everything (except the fasteners!) was imperial. How wierd is the note "28x Tap M6 thru on 2.50" centers"? We should ABOLISH Imperial units. Even the guys who invented this nonsense (the mother country), gave it the boot years ago.
      Quick, show me 39/64ths of an inch with your fingers.

      Raised with Imperial, but converted to Metric. After all, everything in the system is divisible by ten, liquid and dry volume measures are interchangeable, and the system is much more accurate. If the U.S. had converted when they initially said they would back in the Seventies, I would be from the last generation raised in the Imperial System. I am now 60.

      Fundamentally I prefer the metric (ISO) system.

      However I am total against the invention of artifical units of measure, like pascals, kilopascal, megapascals.

      Clearly it should be force/unit area : newtons/sq meter or pounds per sq inch, not kilopascals
