Is 5,280 feet a good unit of measurement? What is it in metric system?
An inch is roughly the width of a person's thumb A foot is roughly the length of a person's foot A yard is roughly the stride of a single person (one pace) A mile is roughly 1000 paces, having originated from the Roman mille passus, or thousand paces."
I get that metric is easier to convert between units because everything is base 10, but imperial is based on easily quantifiable measures by humans without access to an accurate measuring device, so it has its purpose.
