Exporting stl

In all my other CAD or Hard Surface modeling programs when i export my STL it is the same size that i created it, in Sharper it is not ? A 5" cube is exported as a 1/4"

Change the units to mm. Then export. Your 5" cube will be exported as 5".
To rephrase, your 5" cube will be exported as 127mm which = 5".
