Try to use:

var value = data["USD-INR"].val;

Since you've assigned currency value to the currency variable, you can do:

var value = data["USD-" + currency].val;

use like this way

data["USD-INR"].val

So your ajax will be like

jQuery.ajax({
    type : 'GET',
    dataType: 'jsonp',
    data : {
        q : 'USD-' + currency,
        compact : 'y'
    },
    url : 'http://www.freecurrencyconverterapi.com/api/convert/',
    success : function(data){
        var value = data["USD-INR"].val;
        $('#converted_amount').text(value);
    }
});

You can't use [0], because this is a generalized object, not an array. Use this, instead:

var value = data["USD-INR"].val;

Try this..

function convert_currency(){
    var currency = $('#convertor select').val();
    var conversionSpec = 'USD-' + currency;
    jQuery.ajax({
        type : 'GET',
        dataType: 'jsonp',
        data : {
            q : conversionSpec,
            compact : 'y'
        },
        url : 'http://www.freecurrencyconverterapi.com/api/convert/',
        success : function(data){
            var value = data[conversionSpec].val;
            $('#converted_amount').text(value);
        }
    });
}
$(document).ready(function(){
    convert_currency();
    $('#convertor select').change(function(){
        convert_currency(); 
    })
});
