Abstract - Quantum Metrology Triangle experiments combine the three quantum electrical effects that are relevant in metrology, and thus enable a fundamental consistency test on the validity of commonly assumed relations between fundamental constants of nature and the quantum electrical effects. This paper reviews the history, results and the present status of Quantum Metrology Triangle experiments and their perspectives. Possible implications for the knowledge on fundamental constants and the quantum electrical effects are discussed.
