     2. The point from which the graduation of a scale, as of a

     Note: Zero in the Centigrade, or Celsius thermometer, and in
           the R['e]aumur thermometer, is at the point at which
           water congeals. The zero of the Fahrenheit thermometer
           is fixed at the point at which the mercury stands when
           immersed in a mixture of snow and common salt. In
           Wedgwood's pyrometer, the zero corresponds with
           1077[deg] on the Fahrenheit scale. See Illust. of
           Thermometer.
           [1913 Webster]

     Zero method (Physics), a method of comparing, or measuring,
        forces, electric currents, etc., by so opposing them that
        the pointer of an indicating apparatus, or the needle of a
        galvanometer, remains at, or is brought to, zero, as
        contrasted with methods in which the deflection is
        observed directly; -- called also null method.
  
     Zero point, the point indicating zero, or the commencement
        of a scale or reckoning.
