> In what way does you knowing that your foot is not a foot long undermine an argument about accuracy vs precision? I know people whose feet are barely half as long as mine. So what exactly am I or others supposed to use as a foot unit? Something in between or rather towards the smaller feet? Tell a native Dutch person to use like two thirds only while telling some native Asian to use more like 1.3 foot as a foot? And on top of that not even their their own but the average of each, because you don't want to get it wrong by a factor of two? Yeah, who cares if it's 100 foot or 200 foot. Accuracy, right? A meter is easy to remember or to guess with a lot less variation. And if you are fancy enough, you could use a scale for example to get it accurate. A lot of other things actually, too. The magic of definition and derivation. But I am sure a foot can also be derived from Spanish tomatos or something. > analogy to programming How many foot is the circumference of the average straw man? > Imperial measures have their place [...] For example?
