All measurements are uncertain because they are subject to various sources of error, including limitations in the measuring instruments, environmental factors, and the inherent variability in the phenomena being measured. Even the most precise instruments have a margin of error, which can be influenced by calibration, resolution, and the observer's technique. Additionally, the process of measurement often involves approximations and assumptions that can introduce further uncertainty. Therefore, recognizing and quantifying this uncertainty is essential in scientific and practical applications.

When scientific measurements are made, they are reported using all certain digits plus one estimated digit, which reflects the precision of the measurement. This practice helps convey the degree of uncertainty inherent in the measurement process. The last digit reported is typically the most uncertain and indicates the level of precision of the measuring instrument used. This convention ensures clarity and accuracy in scientific communication.
The uncertain digit is the last digit in a measurement that is not known with complete certainty. It reflects the limitation of the measuring instrument used and indicates that there may be some degree of estimation involved. For example, if a ruler shows a length of 12.3 cm, the '3' is the uncertain digit, suggesting that the actual length could be slightly more or less than this value. This concept is important in ensuring accurate representation of precision in scientific measurements.
Certain digits refer to the digits in a numerical value that are known with complete accuracy, as opposed to uncertain or ambiguous digits. In measurements, certain digits include all the digits that can be confidently reported based on the precision of the measuring instrument, plus one estimated digit that reflects the measurement's uncertainty. For example, in the measurement 12.3 cm, the digits '1', '2', and '3' are certain, while the last digit is considered uncertain.
