Precision of a measurement represents the numerical values which represent the dimensions of the instrument measured more accurately.Precised values are nearer t accuracy with negligible error.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Precision and accuracy do not mean the same thing in science. Precision refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the correctness of a single measurement. It is determined by comparing the measurement against the true or accepted value.
because they are both a reliable measurement and is both accurate and precise

If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
Reliability!

precision and accuracy
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
