It does not make sense, giggle.
As much as it does not make sense to…
…ask if the metric is true & the imperial system/s fake.
If the Cartesian (
Descartes had strange experiences with letters on a train) coordinates are true and the polar coordinate systems of geometry that are non-Cartesian are false.
One geometry can not be truer than another geometry.
It (one over the other) can only be more convenient.
There is nothing wrong with a bit of convenience.
