The numerical assessment of a person's willpower has always remained an urgent problem in psychology. Diagnosing the state of willpower is useful in all areas of activity. This problem, however, has not yet been resolved. The purpose of the study is to build metric scales intended for such an assessment. Three interrelated concepts have been introduced: the power of independent volitional quality, the power of will expression and will power. To record the numerical characteristics, it is proposed to use two types of measuring grid – natural and standard metric scales. The need to use a natural scale is explained by the specifics of a particular measuring instrument. The standard scale compares measured volitional characteristics. A convenient unit for measuring willpower is proposed.
