Units and Measurements
In this chapter we will study about:
• Physical Quantities and Units
• Accuracy, Precision and error in measurement

Accuracy refers to how closely the measured value of a quantity corresponds to its “true” value. Precision expresses the degree of reproducibility or agreement between repeated measurements. Measuring devices are used to measure a certain quantity like length, time etc.
