      The paper offers the equation of state (EOS) for the description of pressures and internal energies in a wide range of densities and temperatures. The thermal components of pressure and energy are represented by tables in a uniform logarithmic net with the bicubic node interpolation. The potential components are represented by the cubic spline on a uniform grid, which density is higher than the normal one. To calculate pressures and energies behind the tabulation domain, simple extrapolation formulas are suggested. The GLOBE equation of state can be used in codes for the continuum dynamics simulation. The equation of state functionality is demonstrated by the example of describing the properties of copper.
