The GoldSim Units Manager

The GoldSim Units Manager allows you to view all of the units that GoldSim recognizes. You can also use the Units Manager to add new units if necessary.

You can access the Units Manager by selecting Model|Units… from the main menu, which will display the following dialog:

Clicking the Plus sign next to a category expands the category to show its units.

There is also a button in the Advanced toolbar for accessing the Units Manager:

The Units Manager dialog initially displays the unit categories in the model. A unit category has a name and a specific set of dimensions (displayed in the Description column). The abbreviations for the dimensions are as follows:

Dimension	Abbreviation
Mass	M
Length	L
Time	T
Temperature	t
Current	C
Amount*	A
Luminosity	l
Angle	<
Currency	$

*Used for a quantity of matter (i.e., moles)

Note: A category does not need to have dimensions. It can be dimensionless.

If you expand a category (by clicking on the category folder's "+"), the units in that category are displayed:

When a category is expanded to show units, the first column contains the unit's abbreviation, the second contains its description, and the third contains the conversion factor between the unit and the "internal units" for that category (e.g., SI units).

By default, GoldSim only shows the primary SI unit (e.g., m for length). However, GoldSim recognizes all of the SI unit prefixes. If you check the Show all SI unit prefixes box, they will also be displayed:

SI units are displayed in blue in the dialog.

Note: The Remove button on the dialog is for deleting units. However, you cannot delete the built-in units (and the button is greyed out when these units are selected). Only custom units that you have created can be removed.
