Here's my simple fuel consumption calculator and converter. It's very useful for people who use units other than the US standards of US gallon and Miles when comparing results with others. - Converts between all common fuel consumption units, MPG US, MPG UK, Km/L and L per 100k. - Converts volume in Litres, US Gallons and UK Gallons. - Converts distance in Miles and Km. Should run on any Windows computer (Windows 95 through to Windows 7). Just unzip the exe file to any folder and make a shortcut to the desktop (or unzip it directly to the desktop if you prefer). To use the program just enter your data into any one of the fields (eg MPG US) and when you exit that field all the other relevant fields (eg MPG UK, L per 100k etc) will automatically update with the correct conversion. It works the same way for the fuel volume and distance fields which are on an optional pop-out panel (see screenshot). If you've entered fuel volume and distance data then you can optionally click the "calculate" button to compute the fuel consumption in all four available measurement units. BTW. This program is meant to be non-intrusive on your system. It does not need to "install" itself on your computer to run. It does not write anything to the hard drive (apart from the program file itself) nor does it make any changes to the system registry (or anything else for that matter). So you can use it with peace of mind.
