Accuracy

For instance, measurements of 22.1 in. and 22.10 imply different levels of accurancy.


The first measurement of 22.1 in. suggests that the measurement was made by an instrument accurate only to the tenths place.

The second measurement of 22.10 in. suggests that the measurement was obtained with instrumentation capable of reading to the hundredths place.


The number 0.4020 defines the fourth-place accuracy of the reading.


In the laboratory environment, the level of accuracy can vary from one instrument to another.
