CMV: There shouldn't be anything other than the metric system.

Posting this because I'm genuinely curious about Imperial systems advocates' POV. 

The metric system is much more precise, and the breakdown of units makes much more sense. 

Distance for example: there are 10 millimetres in a centimetre, 100 centimetres in a metre, and 1000 metres in a kilometre. 

Versus the imperial system:   
There are 12 inches in a foot, 3 feet in a yard, and 1760 yards in a mile....what? And if you want to go smaller than an inch, or between yards and miles, then you need to bring in fractions. 

The benefits of being precise far outweigh the benefits of less precise units of measurement, which I only see as being able to generalize (which you can do using the metric system as well). 

If we phased the Imperial System out everywhere, we would have no use for teaching it, and we would have little need of it in society.

Benefit of the imperial system (and base 12 system in general): They are divisible by more numbers.

10 is only divisible by 2 and 5. However, 12, is divisible by 2,3,4, and 6. This is helpful in areas like construction as now you have more options for scale.

EDIT: As other's have pointed out, yes this is only relevant for feet/inches. However, people come across ft/inches conversions frequently enough to warrant a conversation about its benefit.
