Fundamental and derived physical quantities are geometrized on the basis of the hypothesis of global stationary state of our Universe. A new (L) system of physical quantities based on a single quantity (length) is created and developed. Numerical values of seven base units as well as fundamental physical constants are calculated in the L system. We give a geometric interpretation of fundamental notions of macro- and micro-mechanics and explain a large number of physical phenomena of the macro- and micro-worlds, for example, the principle of uncertainty, the microwave background radiation, the black and white holes, the red shift of galactic objects, the Big Bang, the emergence of matter. Also, we estimate the speed of gravitation of the systems «electron-electron», «proton-proton», and others.
