Definition & Meaning of Significant Figures
Significant figures, often referred to as sig figs, are the digits in a number that convey meaningful information about its precision. This includes all non-zero digits, any zeros between non-zero digits, and trailing zeros only when a decimal point is present. For example, in the number 0.00456, there are three significant figures: four, five, and six. The leading zeros do not count as significant figures. Understanding significant figures is crucial for ensuring that calculations reflect the accuracy of the measurements used.
