Common Misconceptions

Significant figures are a way of expressing the precision of a measurement or calculation. They are denoted by the number of digits that are known to be reliable, with the last digit being an estimate. For example, if a measurement is reported as 3.45 cm, the number 3 is certain, 4 is likely, and 5 is an estimate. This system allows scientists and researchers to communicate the level of precision in their measurements and calculations, making it easier to compare and combine data.
