Ah, let's keep machine-readable info in machine-readable fields (like
unit) and let's have human-readable info in human-readable fields
(which would be description in this case).  I submit

  unit: <empty>
  description: Angular momentum relative to the sun

even for humans is preferable to

  unit: Sun
  description: Angular momentum
