The following code creates a NumberFormatInfo and change the group separator from a comma to a space, then use it to format a number to three decimal places: using System; using System.Text; using System.Globalization; class Sample { public static void Main() { NumberFormatInfo f = new NumberFormatInfo(); f.NumberGroupSeparator = " "; Console.WriteLine(12345.6789.ToString("N3", f)); } } The output: 12 345.679
