the estimated digit in 0.503 is 3
Glomerular filtration rate (GFR) is a measurement of how well one's kidneys are functioning. It is typically estimated on the basis of serum creatinine levels. One can learn their estimated GFR by visiting their physician.
inches for length measurement, and seconds for angular measurement
A measurement close to true size is referred to as Precision Measurement.
Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.

There need not be any estimated digit but, if there must be one, then it is the last digit: 3.
Your measurement should include one estimated digit.
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.
The estimated digit in 42.50 g is the last digit, which is 0. The value is expressed to two decimal places, indicating that the measurement is precise to the hundredths place. Thus, the estimated digit reflects a level of uncertainty in the measurement, suggesting it could range from 42.495 g to 42.505 g.
0.503..the 3
The last digit in a measurement indicates the level of precision or uncertainty in the measurement. It is typically an estimate and can vary depending on the instrument's precision or the person taking the measurement. The other digits are considered to be more reliable and accurate in conveying the measurement value.
A pointless exercise! If it has been measured exactly then what is the point of adding one digit which has been estimated?
The significant figures in a measurement include all digits measured exactly, plus one estimated digit.
Yes, but then there is no point in using an instrument that is that accurate!
The figures described are known as significant figures or significant digits. They include all the accurately known digits in a measurement, along with one estimated digit. This concept is crucial in scientific measurements and calculations, as it indicates the precision of the measurement. For example, in a measurement of 12.3, the "12" are exact digits, while "3" is the estimated digit, making three significant figures in total.
Measured values are reported using significant figures, which include all known digits plus one estimated digit. The known digits are the reliable figures determined by the measurement instrument, while the estimated digit reflects the uncertainty in the measurement. For example, if a length is measured as 12.3 cm, the "12" are the known digits, and "3" is the estimated digit. This convention emphasizes the precision of the measurement and communicates the level of uncertainty inherent in the value.
