All measurements are estimations, since it is not possible to measure anything with 100% accuracy, although some things can be measured with a very high degree of accuracy. There is always some limit to the significant digits with which a measurement can be made. You might measure the weight of your sample to the millionth of a gram, or conceivably to an even higher degree of accuracy if the experiment requires it, but you cannot measure it to the last atom. There is a limit to even the finest scale.
