Why is 12 inches called a foot? Is that the average length of a human foot or so!

" The popular belief is that the original standard was the length of a man’s foot!. This is most likely true, but when local authorities and national rulers began calibrating and defining measurements, the foot of no human being was probably used as the basis!. In rural regions and without calibrated rulers, many units of measurement were in fact based on the length of some part of body of the person measuring (or for example the area that could be ploughed in a day)!. In that sense, the human foot was no doubt the origin of the measuring unit called a "foot" and was also for a long time the definition of its length!. To prevent discord and enable trade, many towns decided on a standard length and displayed this publicly!. In order to enable simultaneous use of the different units of length based on different parts of the human body and other "natural" units of length, the different units were redefined as multiples of each other, whereby their lengths no longer corresponded to the original "natural" standards!. "

Note how often it stresses 'some part of the body' lolWww@Enter-QA@Com

Before we used accurate measurements, distance was measured in the length of the top joint of your thumb (inch), the length of your sandalled foot (feet) and the length of your outstretched arm - which was near enough your stride (yard)!. It was only after many hundreds of years some jobsworth decided to standardise it all!.Www@Enter-QA@Com
