What is the standard rail gauge value in millimeters?

Explanation:
The gauge is the distance between the inner faces of the two rails. The widely adopted value for this standard gauge is 1,435 millimeters, which is about 4 feet 8.5 inches. This size is used on most mainline railways around the world to ensure trains and rolling stock can move between networks without compatibility issues. The other numbers listed are not the globally standardized gauge, though some regions historically used slightly different widths.
