>My client wants me to place a metric conversion tool in the application we're developing. Seems to me that this would be out there already. If anyone knows where I can get one I'd appreciate it.

I remember there was one VFP form which did any-to-any conversion, it shipped with VFP in the Samples directory. Just don't torture me to confess which version was it, may have been 3.0 or 5.0... it was long ago.
