Options | Units

 

 

This menu selection sets the units for data entry, display, and graph drawdown axes.

If Prompt for Units Before Data Entry is checked, this dialog will be displayed prior to entering data from Edit | Aquifer Parameters or Edit | Time and Drawdown.

Using User-Defined Units

 

Super Slug accepts user-defined units for transmissivity and hydraulic conductivity. To create a user-defined unit, enter the unit label in the box marked Label. The label is the text that appears to describe the units. For example, the label for meters per day could be meters/day, m/day, or meters per day. Then enter the unit conversion factor. This is a number user-defined units are divided by to get meters per day for hydraulic conductivity, square meters per day for transmissivity, or cubic meters per day for flow rate. For example, if user defined units for hydraulic conductivity were feet per day, the conversion factor would be 3.2808 because hydraulic conductivity in feet per day is divided by 3.2808 to get hydraulic conductivity in meters per day.
