EXAMPLE
First, the desired unit (column 1) and the desired number of decimal places (dp) have to be specified,
along with the application's gear ratio and its feed constant (if applicable). The feed constant is then
displayed in the desired positioning units (column 2). Finally all values can be entered into the
formula and the fraction can be calculated:
