You can use the Percentage Custom Numeric Format String. This will do it without you having to multiply yourself.

For example, you can do:

double value = 0.152;
string result = value.ToString("#0.##%");

If your locale is set to European (my guess based off the format you wrote), you'll get a string with the value of "15,2%".

You can also just use the Standard Percentage ("P") Format String, if you're happy with the default formatting.

Take a look there : Custom Numeric Format Strings

 double number = .2468013;
Console.WriteLine(number.ToString("P", CultureInfo.InvariantCulture));
// Displays 24.68 %
Console.WriteLine(number.ToString("P", 
                  CultureInfo.CreateSpecificCulture("hr-HR")));
// Displays 24,68%     
Console.WriteLine(number.ToString("P1", CultureInfo.InvariantCulture));
// Displays 24.7 %
