General options
	Input format     Text box entry     Free format entry         delimiter	Text box entry provides an entry field for each coordinate to be converted. Free format entry provides a single entry field into which all the coordinates can be typed. (This is more useful if the coordinates are being copied from the clipboard, for example) For free format text specify the character to use to separate input columns.
	Output format     Formatted     Unformatted         delimiter	Choose formatted to display the output coordinates as a normal web page, or unformatted to return the coordinates in a simple form suitable for copying to spreadsheets or other documents. For unformatted text specify the character to use to separated the columns.
	Output precision (metres)     1.0     0.1     0.01     0.001     0.0001	Select the approximate precision used for the output coordinates. Note that this affects only the number of digits displayed, not the actual accuracy of the coordinates.
	Points have names/codes     No     Yes	Select this option to enter a point name (or code) for each coordinate
	Show input coordinates in the output     No     Yes	If this option is selected the input coordinates will be copied in the output.
