WebSep 22, 2024 · Precision refers to the degree of uncertainty in a measurement. For example, a mass measurement of 48.26 g has an uncertainty of ±0.01 g, while a measurement of 48.3 g has an uncertainty of ±0.1 g. Since the measurement of 48.26 g has less uncertainty, it is the more precise measurement. WebApr 12, 2024 · Entanglement and uncertainty relation are two focuses of quantum theory.
