by declaring a global variable as static you hide it from other files. Its declaration is only visible to the function defined in the same file. other file's functions cannot see this variable.

If you would like to use a global constant variable, then static global variable is useful.

like a constant you mean? i think its useful when your program uses formulas. there is always a need for constant variables there. when its global, every program code block knows the variable (therefore no initialization and data type declaration needed everytime that variable is called). when its static, it doesn't change (like in pi = 3.1416...). hope this helps.
