> 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,
