Everyone's foot is a different length, many people even have two feet of different length. So why the fuck do we measure distance in feet? Is it seriously a good idea to base a system of measurement off of the the length of some dead king's fucking foot?
_Edit: Popular opinion I guess, judging from the poll. Making the edit for some individuals who had an issue with that claim._
Metric System is far superior, the numbers make sense and doing the math in your head with metric system is way easier.
The Foot method - and Fahrenheit temperature for that matter - both seem entirely arbitrary and completely fucking stupid.
There should be a better reason for using a system of measurement than "but muh tradition / but muh being different!"
