It's a weighty issue.

Pretty much every country in the world uses the metric system for measurement — having a universal system would be like having a common language across the world, making it easier to communicate, trade and invest. So why doesn’t the US want to commit to the metric system? Technically, it already has — it’s officially the “preferred system of weights and measures for United States trade and commerce”. But the change has never been made compulsory for everyone, so most of the country continues to use the imperial system.

  • I grew up knowing only imperial measurement system. (Even then I thought the use of imperial fractions was frustrating and ridiculous) Took me less than 2 weeks in Europe to be fluent in metric. Rational and logical system.
  • I was born and raised in the U.S went to live to Argentina when i was 15 been using the metric system ever since. Went back to the states after more then 20 years and i can't believe i ever used that crazy imperial system. Metric system way easier to learn and understand

    Imperial system is like that one teacher who loves to overcomplicate things just cause he feels like it.

    I'm glad I work in computers. The whole world uses the same bit and byte units. -What about date formats? -Fu....
  • @Lowkey_ID
    A sign in a machining shop said "The US is actively implementing the metric system, one inch at a time."
  • @ACBlackJ0ck
    Imperial or Metric? The World: "Metric" US: "Imperial" UK: "...Yes"

    I wonder why weather sites still shows temperature in Fahrenheit? Why not Centigrade? It is so easy to understand. Let me tell you at 0 C pure water freezes. At 100 C it boils.
  • @akfr0zen
    Honestly, we had a meeting and decided to piss off the rest of the world by using the imperial system and dropping the u in the word color.

    The Federal government had officially converted, but handles it (ever since Carter is gone) in a way which intends to deter others from doing so. They keep using the Imperial system, but translate every measure in the most awkward way, seemingly "precise". This way, I have seen signs in national parks saying "ELEVATION 609.6m (2000 ft)" and even "WATER-> 15.24m (50 ft)". Thus making people reason that the Imperial system is simple, while the metric one is something only rocket scientists in white frocks can understand. Meanwhile, in the US a problem like "how many 100ft steel bars are needed to make a 3 mile rail?" still makes qualified engineers reach for their computers, while in the rest of the world, any fourth grade child can easily answer the similar "how many 50m steel bars are needed to make a 5km rail?"

    Actually the US was supposed to switch to metric as far back as the late 1700s. Thomas Jefferson was in talks with France about the metric system. He requested France to send a definition of the gram and meter. To make a long story short, there were two attempts to get these samples from France to the US. One ship was looted by pirates and a second ship was lost in a storm. By the third attempt of sending the sample, the proponents behind the first attempts at metric have died and the cause died with them.

    1 mile is 1760 yards, 1 yard is 3 feet, 1 feet is 12 inch and than you just start fractioning it till you have your head burst over the question whether 39⁄64” is smaller than 5⁄8” or not. Really makes sense.
  • I don't understand why Americans are scared by the metric system, yet it's easier and more logical!
  • @isaaccboyd8887
    I live in America and I absolutely hate the imperial system. I am the only person I know how normally uses kilograms and meters in America. I wish more people saw how using 10x and .1 is a lot easier then 1/16th and 12x

    Don't Include Myanmar - it has largely metricated now!

    Slogan for metric system: We bring to you the metric system -"Because 15 cm sounds longer than 6 inches"
  • @davidweber5833
    It reminds me of how hard it was, coming from the U.S. as a middle-schooler, to learn the UK Pounds and Shillings. Then the UK went decimal and counting the correct change was no problem.

    A colleague of mine is an electrical engineer in Nevada (I think), where the electricity company lays cables in metres, while the water company lays pipes by the yard. Due to errors in transcribing drawings they are constantly digging each-others infrastructure up. :-)
