Do you mean how do I convert, for example 18 months into 1.5 years? or 9 months into 0.75 years? If so, that's a pretty straightforward calculation - divide your number by 12 and, perhaps, express the value to 2 decimals points.

If that's not what you meant perhaps you can elaborate on your requirement?
