the earth rotates 360 degrees every day, yet it has moved more than 360 inches... these are unrelated units of measurement, one is angular, one is linear
imperial is not linear it is proportional, you're just full of mistaken assumptions.
Depends on what you're measuring. I rather measure angles in imperial than metric.
You measure angles in degrees or radians
1 inch is roughly equal to 1 degree of rotation.
That's just one radian divided by 12? means nothing
imperial is not linear it is proportional
no, imperial is a system of absolute units, just as metric is a system of absolute units, each is divisible into different values
proportions are ratios of absolute units, like a map, 1inch per mile, 20 miles per gallon
Imperial is a proportion based measuring system, it's better for cooking as you can eye ratios pretty quickly and it's almost as good as having a scale to measure out weight.
No, proportions are inherently neither imperial or metric. "proportions" are better for cooking, but you are still using the absolute value of a cup, the cup could be 200ml, it would work the same
I just showed you how computers calculate a car's alignment btw.
that still means nothing without defining a third variable like radius or circumference
Draw a one foot line projecting from you on the center of the earth's axis, the earth rotates 1 degree for every inch that line move
that makes no sense?
earth radius 6,371KM, circumference=40,030KM, 1 degree of rotation = 40,030/360 = tracing an arc on the earth's surface at the equator of 111KM ?
increasing the earth's radius by one foot doesn't change that much,

Imperial is based on the Sumerian number system, base 12, which is also used to measure angles. The easiest way to divide a circle is by using whole proportions.
that makes no sense?
Look at the specifications for toe on your car, you'll notice a quarter degree of toe in or out relative to vertical is roughly one quarter of an inch of toe.
Take a unit circle with radius 1ft, the circumference is roughly 36 inches. 37.6 to be exact. If you need quick and dirty estimates, imperial is king.
