This is kind of outside the scope of the converter (which is designed to do a direct 1:1 conversion of FST records to netCDF).
However, it is something that could be of practical value for making public datasets, so might be worth exploring as part of the "gridhacks" mixin.
The danger, though, is that someone will then ask for unit conversion from knots to m/s, which then opens up unit conversion for other fields, and then more general math operations... and there are other tools (for FST and netCDF files) that are better suited for doing these sorts of things.
