@ -30,7 +30,10 @@ Abstraction tower for *xo-unit* components.
- scaled_unit:
a unit involving zero or more dimensions, and associated conversion factor.
- expresses result of arithmetic involving multiple scales.
- can express result of arithmetic involving multiple scales,
by reporting an outer scalefactor
- a scaled unit is 'natural' if its outer scalefactor is 1.
- quantities are represented by associating a natural scaled_unit instance
- scaled_units are closed under multiplication and division.
- multiplication and division commit to a single :code:`basis_unit` for each
dimension.
