BaalChatzaf Posted November 19, 2018 Share Posted November 19, 2018 The kilogram is a mass standard. Since the late 19th century it was defined as something that balances a standard kilogram, a platinum-iridium metal mass kept under lock and key in Paris. The standard K is also kept in a nest of bell-jars to prevent dust and particles in the air from settling on the weight. The new kilogram standard is defined in terms of Planck's Constant used in conjunction current in an electrical weighing device. In short, the standard of mass is now defined solely in terms of physical constants. Please see https://www.nist.gov/si-redefinition/kilogram-kibble-balance for the details. See also https://www.nist.gov/si-redefinition/kilogram-kibble-balance for details on the special scale (Kibble Balance) used to iimplement the new standard and weight against it.

Peter Posted November 19, 2018 Share Posted November 19, 2018 THE standard Kilogram? In Paris? Shouldn't they keep that in Antarctica? No ladies or "chubby guys" want to know their weight in kilograms. Now kilos works for the fashion conscious. Yup Bubba. I'm down to 100, uh I mean 70 kilos since muh wife put me on a diet. If I don't fit into last years pants she gets all oriental on me and says things like, "No cookie. No nookie." Link to comment Share on other sites More sharing options...

Thomas Jefferson wanted to adopt the metric system for the U.S. but his pro-French leanings annoyed Congress and the system was not adopted.

The metric system is less conducive to creativity than the imperial system. 10 works great for the observation mindset of science techies, but 2, 4, 8, 16, 32, 64, etc., works better for creators.

J Nonsense. Physical science has not suffered one bit from its exclusive use of the metric system. The good part about the metric system as that measurements among like attributes (mass, length, time etc) the different quantities are related by powers of 10. This is not the case with the British System which is the system for non scientific applications used in the United States. We still measure our distances in inches, feet, yards and miles and the quantities have no simple interconvertability. One must remember 12 inches to the feet, 3 feet to they year 1760 yards to the mile etc. Likewise for ounces of weight), pounds, tons. It is a mess, but we can manage it. The only time the issue of measurement really mattered was in a Mars probe where the American engineers used the British system and the parts made in Europe were metric. The probe failed miserably and it cost millions of dollars to place a bundle of scrap on Mars. Link to comment Share on other sites More sharing options...

However binary arithmetic does and the computer folks do well with powers of two. Link to comment Share on other sites More sharing options...
