I seem to recall that in my numerical analysis course 12 years ago, that it was said that your average physical measurement only had 3-5 digits of accuracy. This means that any answer received cannot be more accurate than the input. No. This requires a study of Estimation theory, with enough _different_ measuring devices and a good model you can get much better results than ANY of your input. There are many good textbooks and monographs.
