SysML-1.6: Use of ValueTypes named like units in Figure 8-12 and Figure 8-14 is inconsistent w.r.t. some other specification diagrams and examples (but not necessarily wrong)
Compare with Webel Best Practice:
Webel: SysMLv1.x: AVOID (where possible) ValueType names that are the same as the name of units or unit symbols
SysMLv1.x: ValueType naming: The Webel convention is 'UpperCamelCase' (a.k.a. PascalCase).
Note however:
MagicDraw/Cameo: SysMLv1.x: ValueType naming: The ISO-80000 libraries use 'lower case' (sometimes with spaces for compound units and/or with [scaling] indicated in square brackets).
This trail version of the figure is extended to include information on the assigned units from the ISO-80000 model library.

Snippets (quotes/extracts)
  [SysML-1.6] SysML ValueType adds an ability to carry a unit of measure and quantity kind associated with the value.
  [SysML-1.6] A ValueType defines types of values that may be used to express information about a system, but cannot be identified as the target of any reference.

Webel: SysMLv1.x: AVOID (where possible) SysML Unit names that are the same as unit symbols. Unit names SHOULD start with a lower case Latin alpha letter. Custom Unit names should be a single lower case word or lowerCamelCase.
