• The state or condition of being equivalent; equality.
  • An equivalence relation.
  • The relationship that holds for two propositions that are either both true or both false, so that the affirmation of one and the denial of the other results in contradiction.
  • To be equivalent to; counterpoise.
  • The condition of being equivalent; equality in value; correspondence in signification, force, nature, or the like: as, a universal <em>equivalence</em> of weights and measures is extremely desirable; exact <em>equivalence</em> between different words is rare. Also <internalXref urlencoded="equivalency">equivalency</internalXref>.
  • In <em>chem.</em>, capability of mutual replacement, in chemical combination, of definite quantities of different substances: thus, there is <em>equivalence</em> between approximately 18.07 parts of aluminium, 40.1 of calcium, 46.1 of sodium, and 55.9 of (ferrous) iron in combining with the same fixed quantity of oxygen.
  • To be equivalent or equal to; to counterbalance.
  • The condition of being equivalent or equal; equality of worth, value, signification, or force.
  • Equal power or force; equivalent amount.
  • None
  • The quantity of the combining power of an atom, expressed in hydrogen units; the number of hydrogen atoms can combine with, or be exchanged for; valency. See <er>Valence</er>.
  • The degree of combining power as determined by relative weight. See <er>Equivalent</er>, n., 2.
  • The condition of being <xref>equivalent</xref> or <xref>essentially</xref> <xref>equal</xref>.
  • An <xref>equivalence relation</xref>; <xref>≡</xref>; <xref>~</xref>
  • The <xref>relationship</xref> between two <xref>propositions</xref> that are either <xref>both</xref> <xref>true</xref> or both <xref>false</xref>.
  • To be <xref>equivalent</xref> or <xref>equal</xref> to; to <xref>counterbalance</xref>.
  • a state of being essentially equal or equivalent; equally balanced
  • essential equality and interchangeability
