Significant figures are a measure of precision.

Explanation:

The significant figures of a number are those that have a real meaning and, therefore, provide some information. Therefore, the set of digits that are known with certainty in a measure are called significant figures and are the digits of a number considered non-null.

Any experimental measurement is inaccurate and must be expressed with its significant figures.

In this way, significant figures express the precision of a measuring tool.
