Yup. This is corollary to the other post talking about diameter. If you make a perfect circle with your perfect meter of perfect string, suddenly you can no longer perfectly express the diameter in SI units, but rather it’s estimated at 31.8309886… cm. Nothing is wrong with the string in either scenario.
I’d like to point out that rational numbers can easily be written in finite length, just not in decimal format.
