An uncertain digit is a digit in a measurement that is estimated or not completely reliable, often due to limitations in the measuring instrument or the precision of the measurement.

How do you determine the decimal place of the uncertain digit when making a measurement?

The decimal place of the uncertain digit in a measurement is determined by the precision of the measuring instrument used. For example, if a ruler has markings down to the millimeter, the measurement can be recorded to the nearest millimeter, with the last digit being uncertain. Generally, the uncertain digit is one place beyond the smallest division of the measuring tool, indicating the level of precision. Thus, for a measurement of 5.3 cm taken with a ruler, the "3" is certain, and the "0" in the tenths place is the uncertain digit.

What is uncertain digit?

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.

Why is the last significant digit recorded in measurement uncertain?

Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,
