from the weight-loss-got-easier dept.

From PBS:

The kilogram — anywhere in the world, for any purpose — is based on the exact weight of a golf-ball-sized chunk of platinum and iridium stored under three glass bell jars in a vault in an ornate building outside of Paris. Accessing the vault requires three people with three separate keys and the oversight of the Bureau Internationale des Poids et Mesures, the international organization that oversees the International System of Units.

Despite all of this security, in the 129 years since the International Prototype of the Kilogram was forged, polished and sanctioned as an artifact of measurement, it seems to have lost a tiny amount of material.

[...] On Friday, metrologists — people who study the science of measurements — and representatives from 57 nations will gather in a conference room in Versailles, France to redefine the kilogram. In other words: the way we weigh the world is about to change.

Also at Smithsonian, New Atlas, and Nature.

    Call it whatever you want, measure it however you want, there are two systems of measurement easily available. One of them got us to the moon and the other is metric, some fancy ass ceremony wont change that, unless of course they rename the gram the moonlander.

    One of them got US to the moon and the other got everyone else to Moon and Mars

      So why is it then that the ones who got to the Moon are the only ones who can land on Mars?

    One got you to the moon and very nearly screwed everything up to hell and gone.
    Try again.

    We got to the moon in spite of the crappy, antiquated, confusing mess of a measurement system, you mean.

    At least one Mars mission failed thanks to confusion between measurement systems.

      It's also worth noting that when true precision is desired using inches as a foundation, the preferred fractional unit is the thousandth of an inch -- a base ten value.

        And because it's not confusing enough, I give you the following from Wikipedia, emphasis mine:

        A thousandth of an inch is a derived unit of length in an inch-based system of units. Equal to ​1⁄1000 of an inch, it is normally referred to as a thou /ˈθaʊ/, a thousandth, or (particularly in the United States) a mil.

        That's right, the common verbal shorthand for the millimetre is also used, in north america, as a verbal shorthand for a thousandth of an inch.

    I'm sorry to bust your bubble, but metric got you to the moon:
    https://www.doneyles.com/LM/Tales.html [doneyles.com]
    "Inside the computer we used metric units, at least in the case of powered-flight navigation and guidance. At the operational level NASA, and especially the astronauts, preferred English units. This meant that before being displayed, altitude and altitude-rate (for example) were calculated from the metric state vector maintained by navigation, and then were converted to feet and ft/sec."
