  “exactly”

  uh huh. and how are you measuring that?

    Now the engineers and/or scientists are crying

      Scientists maybe, engineering is all about calling things close enough.

    You don’t need to, it’s defined. (Lol). If you take a circle with a circumference of 1, then its circumference will be 1… I think I might have lost some braincells reading this.

      He obviously meant to say how do you measure that it’s exactly 1m, even when still in a straight line. Exactly being the key word here.

        But is the circumference of the outer circle or inner circle 1m? The wire has a nonzero width.

    I don’t have to measure it. I stick under glass and define it as the standard which all other measurements are derived from.

    I will be measuring it in meters. One. There you go.

      Exactly. Use a laser measure to cut a plank, then use that for reference!

  A nanodegree of difference in temperature will change the length of the metal.

    And this why you don’t touch the thermostat.
