Don't be an ***. Our money system is accurate to 2 digits simply because that's the smallest coin the government mints. The "accuracy" of money is completely arbitrary. If the government wanted to mint coins that are worth tenths of cents (kinda small, maybe put your picture on it?) then it would be accurate to that value. Of course electronic trading can give change of very small values...but again it's irrelevant because money is not something we measure in a physical sense. As time is.

Getting back to the thread, shot clocks are accurate to units, ie any measurement smaller than that is not valid. That is a consequence of the fact that 10ths are not available to us and we cannot know where between the integer values the timing device is.

As for where the significant digits occur - if this concept was limited to decimals only it would be called significant decimals, not significant digits.

Do you think that every measurement is accurate to tenths of units or better?
