Measured values are reported using significant figures, which include all known digits plus one estimated digit. The known digits are the reliable figures determined by the measurement instrument, while the estimated digit reflects the uncertainty in the measurement. For example, if a length is measured as 12.3 cm, the "12" are the known digits, and "3" is the estimated digit. This convention emphasizes the precision of the measurement and communicates the level of uncertainty inherent in the value.

It includes all of the digits that have been measured exactly, plus one estimated digit.
The significant figures in a measurement include all digits measured exactly, plus one estimated digit.
Significant figures are the digits in a measurement that contribute to its precision, including all the digits that are known with certainty plus one estimated digit. For example, if a ruler measures a length as 12.3 cm, the "12" are the digits read directly from the ruler, and "3" is the estimated digit. The concept of significant figures is crucial in scientific measurements to convey the accuracy and reliability of data.
