Let me explain for you idiots out there why pic related is wrong and retarded.
Both measurement systems have their use.
Metric units
>Prioritize ease of calculation.
>Remove conversion factors between mass and energy, mass and volume
>Are totally arbitrary.
Imperial units
>Prioritize ease of measurement
>Are scaled to the human body. (An inch is a finger segment, a yard is a leg, a foot is a foot)
>Are based around convenience, and are intuitive.
Overall, you should use the system of measurement that best fits the situation at the time. For example, sailors used to use miles for lateral distances, and fathoms for vertical distances. This made sense, because their world was a pancake.
Conversion factors are easy, forcing the entire society to use a particular measurement scale in some grand unifying scheme removes the complex particularity of all our innumerable tasks. A machinist will be familiarized with different units than a structural engineer, who will in turn use different scales than a sound engineer. For example, when you measure the thickness of electrical wires, you're not talking "millimeters", you're talking "gauges"
Furthermore, the metric system just uses prefixes to lengthen or shorten their scale. But you can do the same thing with imperial units. You can talk about deca-feet, kilo-feet, mega-feet.....etc. Easy as pie.
