## CIM Issues #6600

### Multipliers

**Description**

There has been ambiguity in the world over the use of "k" and "M" as scalars. According to the official SI UOM standard, "k" is a scalar for "1000". However, in the computing domain, "k" is often taken to mean "1024". The IEC has addressed this by coining new terms. "Kibi" now means a scalar of 1024, and a computer memory might have 1 kibibits or kibiBytes of storage. There are a family of such scalars that need to be supported.

**Proposed Solution**

Add enumerations to Attribute #16 to support kibi, mebi, and other binary scalars to join with the power of 10 scalars.

For example, with Kibi (Ki) being defined as 2 to the 10th power, an enumeration of "210" might be given to Kibi. There is a family of 10 such scalars defined by the IEC which should be incorporated here.

Finally, some attention should be given to percentages. Since the industry already supports percent (1/100) and permille (1/1000), we might consider coining "perkibi" for 1/1024.

If "+210" represents "1024" then "-210" should perhaps represent "perkibi".
