The McDonald Patent Universal String Tension Calculator

How do I use it?

This now needs the user to download the sec.html file, which uses a java script which my website software does not cope with anymore.

Download the stc.html file, then drag and drop it onto a web browser

Click on the pop-up, and choose the instrument and string set closest to what you have in mind. The form changes to display corresponding scale, note, gauge and string type values, and the associated string tensions are calculated.

If you want to fine-tune the default values, overtype the scale length, gauge and the wound/plain popups. The MPUSTC may override some of your settings, but you'll see alerts which explain why this is so. Press Recalculate when you've finished, and the new tension values are displayed.
