The STP conversion tool is available for download at the company’s website and free to all users. Users can calculate any number of configurations simply by choosing the desired input units. First is speed, torque, and power but the STP can also convert speed to rpm or rad/s; torque to oz-n, lb-in, lb-ft, N-cm, or N-m; and power to watts or HP. Information: www.groschopp.com/stp.php.
