Significant figures
In any measurement, the accurately known digits and the first doubtful digits are called significant figures.
Significant figures include all the digits that are known with certainty from a measuring instrument, plus one estimated digit. The known digits are typically the numbers that are fully displayed on the instrument, while the estimated digit represents the precision of the measurement. This convention helps convey the accuracy of the measurement and indicates the level of uncertainty. For example, if a ruler shows 12.3 cm, the "12" is certain, while the "3" is the 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.
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.
The digits of pi are known to more than a trillion (1012) digits, but it is impossible to state all of them in this forum.
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.

the comparison of unknown quantity against fixed with known quantity is called measurement.
The smallest measurement of time known to science is called a Planck time, which is approximately 5.39 x 10-44 seconds.

Significant figures and significant digits are terms used in numerical calculations to indicate the precision of a number. Significant figures refer to all the digits in a number that are known with certainty, including both non-zero digits and zeros that are between non-zero digits or at the end of a decimal. Significant digits, on the other hand, refer to all the non-zero digits in a number, excluding any leading or trailing zeros. In essence, significant figures provide a more accurate representation of the precision of a number compared to significant digits.
The identity of the Pharaoh Menes is not known with certainty. As such no one knows if he had siblings.
The digits of pi are known to more than a trillion (1012) digits, but it is impossible to state all of them in this forum.
Jewels are weighed in units of measurement called carats. But the weights are still called weights.
There is 5 trillion digits of pi.
