New equation of the saturation pressure for water is formulated and compared with the standard values of the new Skeleton Tables established by the Sixth International Conference on the Properties of Steam (1963). This new equation has a form of the simple fractional expression which can be easily calculated by an electronic computer, and covers the whole range of temperatures between 0°C and 374.15°C with a single equation. This equation has been adopted as a part of the internationally agreed 1967 IFC Formulation for Industrial Use which are the basic equations for the new International Steam Table. Also reported are values of the heat of vaporization for water calculated from the new equation of the saturation pressure.
