%X In this paper we propose a numerical scheme to solve the one dimensional nonlinear Klein-Gorden equation. We describe the mathematical formulation procedure in details. The scheme is three level explicit and based on nonstandard finite difference. It has nonlinear denominator function of the step sizes. Stability analysis of the method has been given and we prove that the proposed method when applied to one dimensional nonlinear Klein-Gorden equation, is unconditionally stable. We illustrate the usefulness of the proposed method by applying it on two examples.
