    which does not fit when you go to buy products in Europe or the Caribbean... go try to buy 3/4 inch conduit, and 12 guage wire... they will give you 2.5mm wire and 20mm pipe usually... but sometimes will sell you 25mm pipe instead...
    You might be better off with 4mm wire as well...but that is not actually 10 guage wire... lol so amps dont work, etc and so forth...

    So you try to use the BS 7671 tables for 120 volt systems...not easy either, but easier, and there is a formula in the Onsite Guide that tells you how to convert some things for 120 instead of the table values for 230..lol...

    My father is vehemently against it, but Metric doesn't bother me. I just want ONE or the OTHER. It's retarded that mechanics and anyone with tools needs two sets of every kind of wrench and socket set.

    But the Brits have to admit they haven't changed fully either, and love their traditional units. Isn't it illegal to sell beer except by the pint, or is that an urban myth that refuses to die?

    Well, when I go to Jamaica or France I drive in Kilometers per hour and using Kilometers to places, but in England I use miles... however, in a way it makes sense because it is Imperial measurements... and the Queen is still in charge of the empire!

    To answer a few questions here.
    It isn't metric, that is based on the metre, a unit of length. But it is a common misnomer used here too. It's SI.
    Yes, we still buy beer in pints in a pub but wine in ml. In a grocery store beer cans are typically 330, 440, 500, or 568 ml, the last being an Imperial pint.
    Yes, we still use MPG for fuel consumption but then our road signs are all in miles. Most cars, maybe all now, have speedometers in MPH and KPH. Speed limits are in MPH.

    Ask the man in the street their height and most likely they will give you in feet and inches. Their weight in stones (14lb) and pounds. Go for a medical and it is done in metres and kg.

    Yes, still a bit of a muddle on some things but, in engineering, it is all SI.

    You're the only person I know that calls it "SI" so please tell me/us what does "SI" stand for?
    If you aim at nothing, you will hit it every time!

    One advantage of legal marijuana is having to know the metric system...
    I agree metric units are much easier to work with, where I work all our lab work is metric, as most places are.
    But with metric its all or nothing, which is why our previous attempts in the US have failed.

    And AWG is baffling in its derivation.

    There is high sense in a " People " using a system that works for them and that they are comfortable with, as opposed to having another system forced on them by external authority figures.
    Metrics are one of the worst ideas that ever was. Even Napolean while in exile saw this simple fact.
    Metrics are a system based on false abstractions of the Earth, as thus they are not harmonic. Anything constructed to metric dimensions will both look and feel wrong to the sensitive person.
    Celsius is useless for HVACR work, and problematic. Bar is the worst of all and totally useless.Seeing Mollier diagrams written in Bar is a complete joke.
    There is nothing worse that having to deal with watts when Horsepower is " whats needed." A large volume of current documentation has become near impossible to decrypt.
    The rest of the world is wrong and the USA is correct and the Metric system should be opposed and removed from as many localities as have the sanity to do so.
    Metrics are fully infuriating and were only of very limited use in the Chemistry lab. If you go digging into other areas of analytics, it will be discovered that there are many problems with many of the units of mesure, and they in fact cannot be used helpfully at all for some types of work.
    I will not speak to people in metric terms nor will I allow metrics loose in my shop.
    Microwave Radiation Dangers should be openly discussed

    So we should resurrect the cubit? Would that make you happy?
    Or maybe rods, poles, and perches?

    The word metric is for measurement, not specifically length. I always assumed the meter comes from the metric system, not vice versa. Yes, it's the modern International System, or SI, also, but it's not wrong to call it the metric system. EVERYONE knows what it means.

    When we talk about the metrics of a baseball pitcher, or anything, we aren't referring to measurements of length usually.
