Abstract
The problem as to when two noncommuting observables are considered to have the same value arises commonly, but shows a nontrivial difficulty. Here, an answer is given by establishing the notion of perfect correlations between noncommuting observables and applied to obtain a criterion for precise measurements of a given observable in a given state.
