Easy. Take a wire that is exactly 1 meter long. Form a circle from the wire. The circumference of that circle is 1 meter.

"exactly"

uh huh. and how are you measuring that?

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.
