Since there are 2 conversion there, it should be extra num and unit. Eg. num1, unit1, num2, unit2.

Answer 2

But your program has just let us select one of the conversion?

Answer 3

I mean that after selecting it could print more than one values for example if I enter 5 km it only displays 5000m.
How to make it display both in metres and miles.
I did this but the second setNum and setUnit overrides the previous one and only displays in metres.
if(unit=="km")
{
   setNum((num/1.609));
setUnit("miles");
setNum(num*1000);
setUnit("m");
}

Answer 4

Thanks for answering.
So if I want to add more conversions I have to add more variables I was wondering if there was an array or something to do this.
