    Hmn…

    You’d need to redefine the derived SI Units, or take new measurements for newly derived units. Newtons, joules, pascals, hertz, coulombs, watts, volts, ohms, farads, siemens, webers, teslas, henrys, becquerels, grays, sieverts, and katals.

    Also not to mention motion and heat.

    You could say there’s a large amount of pressure to not change, or that it’s a high “bar”…

    I hope you smiled, because that is one joke I will not be making again.

      You don’t need to redefine any of them if you don’t change the length of a second though, right? Because the SI unit for time is the second?

      As long as you just change the definition for non-SI units, sure kilometers or miles per hour changes, but that’s not SI, so nobody cares.

        There are (roughly) 86400 seconds in a day. This metric time describes a day with 100000 seconds. If you don’t redefine the second, then I guess we’ll just redefine the day, right?

          100 seconds to a minute, 96 minutes to an hour, 9 hours in a day?? Metric with rounding.
