Well you have me- from proto-european which means to measure.
Then you have metrical (metricus/metrikos from Latin/Greek) that means to measure rhythm in poetry.
Mētrum/Metron again from Latin/Greek meaning “measure, length, size, limit, proportion”
Then “metre” which is originally a unit of length. Then you have a “metre stick” which is a stick used to measure a metre. You can blame the French for basically calling it a “measurement stick” but it refers to a very specific measurement.
Then you have the -or suffix in Latin which means “to have to do with” or “to pertain to”. Then that turns in to -re and -er in Old English.
And like every else Brittan used both for centuries before deciding one was “right” and everyone else is at fault for the other way (just like how “Soccer” is a British term). Famously Shakespeare used both -re and -er.
Lastly, the US uses the metric system for its professions. It’s layman’s terms that don’t use metric.
