Cienapps will adapt to your CAD/CAM; whether your software is in metric or imperial, you will be able to import with the unit of measurement you are used to working with.
While Cienapps works in imperial by default, you will easily be able to change this parameter; no need for complex calculation or external conversion tools.
You only have to open the product type window and select those you wish to keep with metric measurement. Once your choices are saved, these products will be imported in metric in your next import. Since the selection is by product type, it is also possible to keep a certain product in imperial in order to ease your transactions with your suppliers using a different unit of measurement.
However, note that it is only possible to work in metric if your CAD/CAM is set up with this unit of measurement. Cienapps does not make the conversion from imperial to metric if your CAD/CAM is already set with imperial measurement.
