Everything You Need To Know About The American Kilogram!

Submitted by: MrOrange 8 months ago in Science


From Veritasium: Back in 1875 The US signed the Metre Convention, which basically committed the country to use the metric system. In return, French scientists sent two platinum-iridium cylinders that weigh 1kg to the US in 1889 (known by their designations K4 and K20 from a set of 40 identical objects that were produced and sent around the world). So even though everything you see and buy in the US is usually reported in pounds, all weights are traceable back to the K20 kilogram (by applying a conversion factor to get to pounds).

excellent post...I can never understand why sme countries persist with non-metric units in day to day use...it's so easy, a stanard base 10 system where length, area, volume and mass are all co-related..1 L of pure water at 4C, at 1 atm = 1kg = 1000 cc...
