Accuracy of Measurement

Accuracy is how close a measurement is to the correct value for that measurement.
Accuracy is the ability of the instrument to measure the accurate value. In other words, it is the closeness of the measured value to a standard or true value. The accuracy can be obtained by taking the small readings. The small reading reduces the error of the calculation.

The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions).
