Creating Unit Groups and Flow Properties

Although the TianGong Data Platform supports users to independently create "Unit Groups" and "Flow Properties" function modules, it should be noted that such custom operations carry high risks and may lead to problems such as unit conversion anomalies and life cycle impact assessment (LCIA) calculation association failures. Based on system compatibility and data accuracy considerations, users are advised to use the creation function with caution, and in principle, it is not recommended to create custom unit groups and flow properties.

The unit mean value should be filled in according to the reference unit of the value reference, and its value is the value of the operating unit converted to the reference unit divided by the value of the reference unit. After completing the unit creation, click save, and the unit group creation is complete.

Notes:
The reference unit is generally the most commonly used unit in the unit group (such as "kg" for the mass group, "m" for the length group). The determined reference unit should open the value reference key at the bottom of the "Create Unit" page for identification.
