Answer 1

AngularJs currencyFilter just formats output. If you want actually convert currency, you need to make custom filter, for example.

Here is possible example:

angular.module('myFilter', []).filter('currencyConverter', [function() {
   function convert(inputValue, currecyId) {
       // Your conversion code goes here
   }

   return function(inputValue, currencyId) {
      return convert(inputValue, currencyId);
   }
});

As @Andrey said, you should build your own custom filter to handle the currency conversion.
Here's a simple demo of how I would build such a thing:

angular.module('myModule').filter('currency', function() {
    var defaultCurrency = '$';

    return function(input, currencySymbol) {
        var out = "";
        currencySymbol = currencySymbol || defaultCurrency;

            switch(currencySymbol) {
                case '£':
                    out = 0.609273137 * input; // google
                    break;

                default: 
                    out = input;
            }

        return out + ' ' + currencySymbol;
    }
});
