     A doorknob of whatever roundish shape is effectively a continuum of levers, with the axis of the latching mechanism—known as the spindle—being the fulcrum about which the turning takes place. Applying a force tangential to the knob is essentially equivalent to applying one perpendicular to a radial line defining the lever.

2. (mathematics) Of two sets, having a one-to-one correspondence.

   Synonym: equinumerous

   • c. 2005, P N Gupta Kulbhushan, Comprehensive MCQ's in Mathematics, page 3:

   • 2006, Joseph Breuer, Introduction to the Theory of Sets, page 41:

     The equivalence theorem: If both M is equivalent to a subset N₁ of N and N is equivalent to a subset M₁ of M, then the sets M and N are equivalent to each other.

3. (mathematics) Relating to the corresponding elements of an equivalence relation.
4. (mathematics, category theory) Of two categories, (informally) such that one is essentially a relabeling of the other; (formally) related by a pair of functors such the composition of the one with the other is naturally isomorphic to the identity functor.
5. (chemistry) Having the equal ability to combine.
6. (cartography) Of a map, equal-area.
7. (geometry) Equal in measure but not admitting of superposition; applied to magnitudes.

equivalent (plural equivalents)

1. Anything that is virtually equal to something else, or has the same value, force, etc.

   • 1977 April 18, Jimmy Carter, President's Address to the Nation on Proposed National Energy Policy:

     Our decision about energy will test the character of the American people and the ability of the President and the Congress to govern. This difficult effort will be the "moral equivalent of war" — except that we will be uniting our efforts to build and not destroy.

2. (chemistry) An equivalent weight.

Sometimes the noun equivalent to denote a comparable option is assailed for falsely implying absence of difference (false equivalence); when this problem arises, the noun counterpart, or a collocation such as rough equivalent or near equivalent, is sometimes a less misleading choice. In some contexts, the nouns analog or homolog are apt.
