I am not set on one approach or another. However, I do prefer something like:
with Linear_Measurement;
...
type Altitude is private;
function Feet (Value : in Linear_Measurement.Feet) return Altitude;
function Miles (Value : in Linear_Measurement.Miles) return Altitude;
...
function Feet (Value : in Altitude) return Linear_Measurement.Feet;
function Miles (Value : in Altitude) return Linear_Measurement.Miles;
...
This suggests an architecture, but a fully detailed solution would include
some package hierarchy and/or abstract type for handling units without the
need to declare all conversions for all dimensions.
