Convert C# software to universal app

We have a small C# software that we would like to convert to an Universal app. This software is quite simple , it calculates altitude corrections for pilots as a function of Temperature and Altitude. This is an initial test project of your programming skills which if satisfactorily could lead to more and bigger projects as our plan is to convert most of our software to universal apps. It is an advantage if you have previous experience from the aeronautical industry.
