      Assume that your length of measure is a string. You can ‘compass’ a circle with one end of the string at the center, and the other ens holding your marking device. Cut out your wheel, mark one point on the wheel for every revolution of the wheel, which is a circumference. You have introduced Pi as a constant.

          What is the formula for a circumference? That is where Pi enters in. If my base unit is a Pharaoh’s dong, and this is the wheel’s radius, a rotation will be 2Pi x (Tut’sDong)

            Pi is just a constant. Call it C.

            You can multiply C by the number of Tutankanmandong.

            Has nothing to do with if you measure with a wheel or a ruler or a string or 27 donkey penises.

            But yeah, if you really want, we can divide anything by pi. Or e. Or any other constant, pick one.

              Of course we can, but if we decide to divide by Pi, can we also end up with an integer in ancient units of measure as is said in the article? A wheel makes sense. Some mythical aliens coming down from hundreds of light years is statistically very unlikely.
