Appendix G. Units and Decimals <br />Units of measure for all variables and the number of decimal places for output variables <br />can be changed using Configure > Custom units preferences. (The number of decimal <br />places displayed for input variables is determined by the variable of highest precision <br />entered in the worksheet.) Changes can be saved as a custom units set and used again <br />with Configure > Units set selection > Custom. Changes can also be applied to the open <br />worksheet without saving a custom units set. Changes apply to all variables in a Units <br />Category as given in this table. Settings for the default English and metric units and deci- <br />mal set are given. All selections are saved with a worksheet or run. <br />Units editor <br />Units category <br />Variable <br />English default <br />Metric default <br />tab <br />Units <br />Output <br />Units <br />Output <br />decimal <br />decimal <br />places <br />places <br />Fuel & <br />Fuel Load <br />.
