To view the properties of an engineering unit in the catalog
-
Navigate to the Engineering Unit Catalog.
-
Select an engineering unit from the catalog.
-
The Properties pane appears.
Descriptions of the properties available for an engineering unit are as follows:
|
Property |
Description |
|---|---|
|
Symbol |
Canonical (standard) symbol used by the system of measurement that the unit belongs to. May contain special characters, such as °F for temperature in Fahrenheit. |
|
Basic Symbol |
Canonical (standard) symbol used by the system of measurement that the unit belongs to. May not contain special characters. |
|
Dimension |
The dimension of the engineering unit, such as Density or Current. |
|
System |
The system of measurement that the unit belongs to. |
|
Offset |
The offset used in linear conversion with respect to the base unit (b in the following line equation: y = mx+b). |
|
Factor |
The scale factor used in linear conversion with respect to the base unit (m in the following line equation: y = mx+b). |
|
IntegralDivisor |
The factor to be applied when integrating a rate with the units [EngUnits/TimeUnit] to a quantity with units [EngUnits]. This factor is called the integral divisor. The default value of 1 assumes a time unit of seconds and ensures that a rate of [Unit/second] is correctly integrated to [Unit]. For a time unit of minutes, set the integral divisor value to 60; for a unit of hours, set the integral divisor value to 3600. The integral divisor is applied similarly to rates or quantities that are not expressed in terms of a time unit. For example, to convert watts to watt-hours, the integral divisor is 1/3600. To convert watts to kilowatt-hours, the integral divisor is 1/3600000. |

User Defined |
Specifies whether the unit is a custom unit defined by the user, or a system unit. |
