No need to multiply by 100. Use this

Console.WriteLine("Display percentage: {0:#.##%}", num);

Use # depending upon the precision.

Use the "P" format, which is hopefully more aware of globalization:

String.Format("{0:P4}", pos); // e.g. 1,000.0000%

You ought to be able to use this format string directly in your Gridview, too, as others have suggested. Since it does the 100x calc for you, though, it should actually work :). Perhaps like this:

<asp:BoundField DataField="Db" DataFormatString="{0:P4}" />

Multiply by 100 and parse the result as a string and format it appropriately...

String parsedNum = String.Format("{0}%", num * 100);

It sounds like you're implicitly asking a Gridview question as well, try:

<ItemTemplate>
   <asp:Label id="Label1" runat="server"
         Text='<%# Eval("Amount", "{0:0%}") %>' />
</ItemTemplate>

 Double yourValue = 0.00065;
 String percentage = (yourValue*100).ToString() + "%";

Well, that really depends on what it's meant to represent in its current form.

It may be as simple as multiplying by 100... but it could also be 10,000 depending on the exact meaning of "Amount".

What would you want displayed for 0.000654345?
