    1kg = double it and add a little lb
    1lb = just under half kg

    1cm = just under half in
    1in = a little more than double cm

    F vs C = give up

      F vs c is easier if you think in bands of temps. 15 C is about 60 F. Each ten degrees difference in F is about 5 degrees different in C. So 20 C is about 70 F. 10 C is about 50 F.

      For above freezing, terrestrial temperatures, Canadians have long depended on the “double it and add 30” rule to understand freedom temperature units while travelling.

      For F and C, there’s a 10% variation from double/divide (5/9 vs 9/5).

      So add or subtract 10% after doing that part.

        I’ve worked in some capacity of manufacturing for a while now so I’ve gotten used to going back and forth. You’ll get it!
        Practice by thinking what the other would be any time someone mentions one.

      1 kg = 2 * lb + 1/5 * lb (lucky for us 5 is a prime factor of base 10)

    Yawn.

    Like this is the first time OP has heard of other units.

    Why do you use Celsius when Kelvin exists?

    Most likely I learned metric long before OP was even born, in the US ( it’s been taught in the US since the late 60’s).

    You want us to throw away all our tools overnight? Recalculate every recipe, re-tool every process (with concomitant errors), etc, etc, etc, overnight? Are you paying for this?

      The US is a big reason for metric being the standard

      They were a founding member of the Metre Convention and wanted a unit that wasn’t British

      To the best of my knowledge, everywhere that has converted so far has just started making new things in metric. Yes, that leaves a weird state where you may see signs in one or the other, for example, but over time it resolves. Tools in other sizes would continue to be made as long as they needed to in order to maintain the old stuff until that gets replaced.

    Metric is for mass and Freedom Units™ are for weight. Because using the same unit of measure for both like metric does just because they happen to be on earth is stupid.

    ELI5: Why some people use term “freedom units” for “imperial units”? They are the same (except gallon and bushel, whatever that may be).

    Can confirm. I have no idea how much I weigh, my height, or what the temperature is outside of imperial units and Fahrenheit.

        You know I hear this a lot but yours is the first time that didn’t seem hugely antagonistic

        Thank you for that

          Well, the way I see it, autism isn’t something a person gets to choose or change, but being angry is. I thought that distinction was important.

            Well you’re wrong in this case, my anger is largely medical and does not respond to treatment. But that’s for making the asshole assumption as usual. Enjoy your block.

            My entire life is filled with people like you who assume I am this way because I enjoy it, as if I would CHOOSE to seethe 12 hours a day, and the decades of isolated social hell I’ve had to endure because of it makes rancid little grease stain replies like yours oh so much more infuriating.

            You’ll give a medical exception to ANY behavior except an angry white man
