Thanks Cath. I am making improvements to the calculator as I go along, and hopefully I will be able to add another few useful functions, such as a Poser units convertor (although this will only be useful when moving the vehicle along the x or z axis, not a combination). I am also going to see about uphill and downhill calculations. If you can think of any other useful functions that need to be calculated for Poser, or converted, will you let me know. R_Hatch, I think for the Yanks I will just make a seperate version with everything in those primitive units, lol. I will sub-name this one the metric version. I am going to test it on a few other spreadsheet programs to see how well it runs. I doubt if it will work on many, as things like Pi are not standard in all spreadsheets. Thanks for the input.
