@alcade Metric doesn't have an equivalent to feet which makes it awkward to measure the height of people. Either you are hundreds of centimeters tall or 1 or two meters tall.
Imperial measurement names also just roll of the tongue better. "Don't move an inch" sounds better than "don't move a centimeter".
@applejack @alcade People do the same thing with time (eg 1 minute 3 seconds).
@xianc78 @alcade "awkward to measure" bro, you have to combine two completely separate units to sensibly measure height
