*** An important note:
We have tested our tools carefully. Nevertheless, we cannot exclude the possibility that errors have crept in with the large number of formulas and links. Also the accuracy of the calculations will depend on the proper use of tables and the accuaracy of the input by the user.  Therefore: All calculations are made at your own risk. We assume no liability for the correctness of the calculated results displayed. In case there are any questions, please contact us via the contact form!
