True but there are also many different types of meters: kilometers, centimeters, millimeters, thermometers, barometers, ... face it: the metric system isn't better
You are right. But the metric system is intuitive. 12 millimeters = 1 centimeter, 3 centimeter = 1 meter, 100 meter is a football pitch, and 1760 meters are a kilometer (I had to google this one because I never know. The designers really missed out at using 1776 meters in a kilometer).
Talk shit about imperial all you want, just remember that the British made it. US was just too busy building a damn country to change units when the new one was adopted by the British and their imperial states.
When I make an Irish coffee, that's definetly not what makes it Irish. Though by coincidence it does end up 1.27 times the size of a regular one, on account of the additives.
Still: the difference between a kilometer and a centimeter is much bigger than the difference between a nautical mile and an Irish mile. And not even all meters are standardized. Thermometers and barometers vary hugely in size
Ah, you must live in the US. Because in the rest of the English speaking world, a metre is a unit of length, and a meter is a measuring device. Note the difference in spelling. ;)
