Notes:
1.    Rc. means: Recalculate, input a new value for one of the known variables and Click the appropriate button while pressing the Shift key to calculate a new answer for the same unknown variable.

2.    The pale yellow buttons are the Multiple-Entry Calculators, use the Extended keys to input that value.

3.    Right Click the light blue buttons to select units or other special setup requirements.

4.    > (e.g. m>Hz), is an abbreviation that means "convert m to Hz".

5.    See the Help file that comes with the RPN Engineering Calculator software for a more complete description of the available functions.

6.    To print this table set the Left and Right print margins as small as your printer allows.
        In Internet Explorer, Click File, Page Setup, and change the margins to something less than 0.75".
