I have made every effort to ensure that all the calculations that form part of this tool are correct and accurate, I have back-tested and checked it against the original source. HOWEVER, I cannot and do not guarantee that the results output from the calculator are correct. You should always double check the results being output – especially if you are using the results for engineering calculations. Finally, if you do discover any bugs in the calculations I would really appreciate it if you would drop me an email at and let me know so I can make the correction.
