Real Attributes of Physical Quantities
- Last UpdatedMay 24, 2022
- 3 minute read
Real attributes can be purely numeric, but often they may be representing physical quantities. The type of a physical quantity is its (physical) dimension.
Attributes of physical quantities are consistently stored in the database in defined database units, irrespective of the current working units, or of the units of any value entered by you. The whole system operates on the expectation that all stored values of physically dimensioned quantities are in their relevant standard database units.
The following table lists the dimensions understood by the system giving:
Their name (or description) recognised by the system,
The assigned hashcode,
The database storage units.
Supported standard units for the quantity
For example attributes of length have a hash code of DIST are stored in mm and other standard units include inch, cm, ft, metre:
