Using King's model, we derived the dynamical masses of six globular clusters. The masses of clusters were calculated from the dynamical length parameters combined with the central velocity dispersion. The dynamical masses are all in the range from 2.5×105M⊙ 2.5×105M⊙ to 1.4×105M⊙ 1.4×105M⊙ . The (M/Lv)⊙ (M/Lv)⊙ , values lie between 1.0 and 1.2, which are typical for galactic clusters.
