Accuracy and precision are very important in chemistry. However, the laboratory equipment and machines used in laboratory are limited in such a way that they can only determine a certain amount of data. For example, a scale can only weigh the mass of an object until a certain decimal place, because no machine is advanced enough to determine an infinite amount of digits. Machines are only able to determine a certain amount of digits precisely. These numbers that are determined precisely are called significant digits. Thus, a scale that could only weigh the mass until 99.999 mg, could only measure up to 5 figures of accuracy (5 significant digits).
