      Common misconceptions

      Some common misconceptions about significant figures include:

      Significant figures are the digits in a measurement that are known to be reliable and certain. They are determined by the precision of the measurement instrument or method used. For example, if you measure a length using a ruler with a precision of 1 mm, the measurement would have 3 significant figures: 10.5 cm. Understanding significant figures involves recognizing the limitations of measurement instruments and methods, as well as the rules for determining significant figures.
