Thus a foot is well the length of a human foot... A cup, is well a cup. An inch is a thumb length.
Not really much of a killer argument: my foot is not the size of someone else's foot. Nor is my cup. Nor is my thumb length.
- hdra 14y agoAgreed. and what can be "measured" by eyeballing it can be measure without. I usually call it "estimating".
- mpyne 14y agoThe problem is that most people don't need to measure things in day to day life, they only need to estimate. Those that do need to measure already know that they have to track units no matter which system of measurement they use (as the difference between entering grams by accident instead of kilograms is 3 orders of magnitude!)
- sp332 14y agoYour foot is much closer to a foot than to a meter. Your cup is more cup-sized than liter-sized. An average guy's thumb is about an inch across, not a centimeter. Having sizes of things that are more common and relateable is important.
- antihero 14y agoYeah but saying that conforming to supposed real objects is ridiculous. Metric is great because it doesn't correspond to anything in particular, thus there can be no mistakes - a metre is a metre!
