To minimize errors in measurements, follow these best practices:
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.
To determine the number of significant figures in a measurement, look for the following:
