You don't want OutputForm as the input to ToString
ToString[1/3] // FullForm
"1\n-\n3"
ToExpression[ToString[#[1/3]]] & /@
{InputForm, StandardForm,
TraditionalForm, OutputForm}
{1/3, 1/3, 1/3, -3}

Evaluating:
ToExpression [ ToString [ 1/3 ] ]
I did not expect negative three!
Bug? or a lack in my understanding?
