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:

The Units Manager dialog organizes the units by unit categories. A unit category has a name (e.g., Area) and a specific set of dimensions An output attribute for an element that defines the dimensionality (in terms of Length, Time and other fundamental dimensions) of the output. (e.g., L2). These dimensions are 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	$

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

By default, each category is expanded a category to show all the units in that category.

When a category is expanded to show units, the first column contains the unit's abbreviation (Name), the second contains its Description, and the third contains it’s Value (i.e., the conversion factor between the unit and the "internal units" for that category, which would typically be an 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 grayed out when these units are selected). Only custom units that you have created can be removed.
