  15.      _uuuu_nnnn_iiii_tttt_ssss converts quantities expressed in various standard scales to their
  16.      equivalents in other scales.  It works interactively in this fashion:
  17.  
  18.           You have:  _iiii_nnnn_cccc_hhhh
  19.           You want:  _cccc_mmmm
  20.                   * 2.540000e+00
  21.                   / 3.937008e-01
  22.  
  23.      A quantity is specified as a multiplicative combination of units
  24.      optionally preceded by a numeric multiplier.  Powers are indicated by
  25.      suffixed positive integers, division by the usual sign:
  26.  
  27.           You have:  _1111_5555 _llll_bbbb_ssss _ffff_oooo_rrrr_cccc_eeee_////_iiii_nnnn_2222
  28.           You want:  _aaaa_tttt_mmmm
  29.                   * 1.020689e+00

  31.  
  32.      _uuuu_nnnn_iiii_tttt_ssss only does multiplicative scale changes; thus it can convert Kelvin
  33.      to Rankine, but not Celsius to Fahrenheit.  Most familiar units,
  34.      abbreviations, and metric prefixes are recognized, together with a
  35.      generous leavening of exotica and a few constants of nature including:
  36.  
  37.           _pppp_iiii       ratio of circumference to diameter,
  38.           _cccc        speed of light,
  39.           _eeee        charge on an electron,
  40.           _gggg        acceleration of gravity,
  41.           _ffff_oooo_rrrr_cccc_eeee    same as _gggg,
  42.           _mmmm_oooo_llll_eeee     Avogadro's number,
  43.           _wwww_aaaa_tttt_eeee_rrrr    pressure head per unit height of water,
  44.           _aaaa_uuuu       astronomical unit.
  45.  
  46.      _PPPP_oooo_uuuu_nnnn_dddd is not recognized as a unit of mass; _llll_bbbb is.  Compound names are run
  47.      together, (for example, _llll_iiii_gggg_hhhh_tttt_yyyy_eeee_aaaa_rrrr).  British units that differ from their
  48.      U.S. counterparts are prefixed thus:  _bbbb_rrrr_gggg_aaaa_llll_llll_oooo_nnnn.  For a complete list of
  49.      units, type:
