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

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

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

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

Gridview, . 100x calc , , :). :

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