The local equivalence of left-invariant metrics with the same curvature on three-dimensional Lie groups \(G_ 1\) and \(G_ 2\) (where \(G_ 1\) is unimodular and \(G_ 2\) is non-unimodular) is studied. A necessary and sufficient condition for these metrics to be locally equivalent is given. From this result follows the existence of homogeneous Riemannian manifolds which have the same curvature, but are not locally isometric.
