Note that (unlike the specification Unit examples) Units here are given verbose names, rather than being named after the unit symbols.
Some ValueTypes are named after general kinds of quantities within the domain; these are used in the sample problem for parametric equations.
Other ValueTypes are named to indicate (as far as possible) the usual symbols of their Units; these are used in the specification examples for blocks with physical values.
WARNING: there are some inconsistencies in the use of ValueType and Unit names in the SysML1.0 specification examples.
