Batch conversion

[Jasper]

Hi all, 
While the requirement might not make sense there is method behind my madness. I need to convert hundreds of jpg images containing critical EXIF info to a TIFF file, but retaining and transferring the info like time and critically the GPS information into the TIFF file.  Can somebody steer me in the right direction to achieve this with what seems to be an extremely powerful Exif tool?

Much appreciated

Exiftool only deals with metadata, it cannot convert images from one format to another.

You don't mention what system you're on.  If you can script, ImageMagick can convert and is available on most OSs.  On Windows, I use IrfanView to convert images, though you may need to also download the plugins.  It has batch convert capabilities.
