Hi, thanks for your suggestion.

I have looked into some perl modules for unit conversion, the Physics::Unit is quite complete but still the "units" program is more complete, which provide around 2526 units of conversion.

Still, the "units" is the preferable choice for the application. I have seen a number of perl module make use of external command line. Aha, I think I have to read their source code and see how they wrap the code. Or is there a tutorial for this ?

Thanks.
