A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
Significant figures represent the precision of a measurement because they indicate the level of uncertainty in a measurement due to the limitations of the measuring tool used. Accuracy, on the other hand, refers to how close a measured value is to the true value. The number of significant figures does not necessarily reflect the accuracy of a measurement, as a measurement can be precise (consistent) but not accurate (close to the true value).
Significant digits in measurement refer to the digits in a number that carry meaning or contribute to the precision of the measurement. They indicate the level of accuracy or certainty in a measurement, with each significant digit representing a reliable and known value.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
Accuracy is important to ensure that the measurement is as close to the true value as possible, while precision is important for ensuring consistency and reliability in repeated measurements. Having both accuracy and precision allows for confidence in the validity of the measurement and the ability to replicate it reliably.
Significant figures are important for indicating the precision and reliability of a measurement. They help communicate the level of uncertainty in a measurement and ensure the appropriate level of precision in calculations. Following rules for significant figures helps maintain accuracy in scientific calculations and reporting.

Significant figures indicate the precision of a measurement, representing the certainty of the digits recorded. The more significant figures a number has, the more precise it is, as it reflects a finer level of detail in the measurement. Accuracy, on the other hand, refers to how close a measured value is to the true value. While significant figures convey precision, they do not guarantee accuracy; a precise measurement can still be inaccurate if systematic errors are present.
Significant digits in measurement refer to the digits in a number that carry meaning or contribute to the precision of the measurement. They indicate the level of certainty in a measurement and help determine the accuracy of the result. The more significant digits in a measurement, the more precise the measurement is considered to be.

If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
Reliability!
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
Significant figures represent the precision of a measurement, including all certain digits and one uncertain digit. Decimal places indicate the number of digits to the right of the decimal point. Significant figures are based on the accuracy of the measurement, while decimal places are based on the scale of the number.
precision and accuracy
accuracy
The number of digits in a measurement that you know with a certain degree of reliability is referred to as significant figures. Significant figures include all the known digits in a measurement plus one estimated digit, indicating the precision of the measurement. For example, if a measurement is recorded as 12.3, it has three significant figures, reflecting a reliable accuracy up to the tenths place. The more significant figures, the greater the confidence in the accuracy of the measurement.
Accuracy is important to ensure that the measurement is as close to the true value as possible, while precision is important for ensuring consistency and reliability in repeated measurements. Having both accuracy and precision allows for confidence in the validity of the measurement and the ability to replicate it reliably.
