    As someone who has written mathematical software, people commonly
    assume various unit definitions and often there are clashes.  In the
    morning I may be working on scientific things where nanometers are
    used, and in the afternoon I may be on my boat and in need of
    nautical miles.
    
    For example, what does 'log' stand for?  Half of us would say log
    base 10, the other half log base e.  'ln' however always means log
    base e, so it is a better term to use as a function name.  ('log10'
    is the most common unambiguous name for common logarithms.)
    
    Likewise, 'nm' is ambiguous in a larger scientific or calculating
    context, hence my recommendation of 'nmi' for nautical mile.
