This Microsoft Add-In provides very powerful unit conversion functionality. It's tight integration with the Excel environment allows easy access through the menus and toolbars. The main unit conversion functionality is available as a user defined function. This can be accessed from the Insert Function dialog or by simply typing it into a cell. Units are defined in a simple text file, which can be modified if new ones are required. However most units are already defined and new derived units can be generated on the fly (e.g. kg.m/s). Dimensional Analysis is used to ensure that the conversion is legitimate. A fully working evaluation with a nag screen is available to download from http://www.unit-conversion.com/downloads.aspx.
