E`quiv´a`lent   Pronunciation: ė`kwĭv´å`lent
a.1.Equal in worth or value, force, power, effect, import, and the like; alike in significance and value; of the same import or meaning.
For now to serve and to minister, servile and ministerial, are terms equivalent.
- South.
2.(Geom.) Equal in measure but not admitting of superposition; - applied to magnitudes; as, a square may be equivalent to a triangle.
3.(Geol.) Contemporaneous in origin; as, the equivalent strata of different countries.
n.1.Something equivalent; that which is equal in value, worth, weight, or force; as, to offer an equivalent for damage done.
He owned that, if the Test Act were repealed, the Protestants were entitled to some equivalent. . . . During some weeks the word equivalent, then lately imported from France, was in the mouths of all the coffeehouse orators.
- Macaulay.
2.(Chem.) That comparative quantity by weight of an element which possesses the same chemical value as other elements, as determined by actual experiment and reference to the same standard. Specifically: (a) The comparative proportions by which one element replaces another in any particular compound; thus, as zinc replaces hydrogen in hydrochloric acid, their equivalents are 32.5 and 1. (b) The combining proportion by weight of a substance, or the number expressing this proportion, in any particular compound; as, the equivalents of hydrogen and oxygen in water are respectively 1 and 8, and in hydric dioxide 1 and 16.
3.(Chem.) A combining unit, whether an atom, a radical, or a molecule; as, in acid salt two or more equivalents of acid unite with one or more equivalents of base.
Mechanical equivalent of heat
(Physics) originally defined as the number of units of work which the unit of heat can perform, equivalent to the mechanical energy which must be expended to raise the temperature of a pound of water one degree Fahrenheit; later this value was defined as one British thermal unit (B.t.u). Its value was found by Joule to be 772 foot pounds; later measurements give the value as 777.65 foot-pounds, equivalent to 107.5 kg-meters. This value was originally called Joule's equivalent, but the modern Joule is defined differently, being 107 ergs. The B.t.u. is now given as 1,054.35 absolute Joules, and therefore 1 calorie (the amount of heat needed to raise one gram of water one degree centigrade) is equivalent to 4.186 Joules.
v. t.1.To make the equivalent to; to equal; equivalence.
Noun1.equivalent - a person or thing equal to another in value or measure or force or effect or significance etc; "send two dollars or the equivalent in stamps"
2.equivalent - the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen
Adj.1.equivalent - equal in amount or value; "like amounts"; "equivalent amounts"; "the same amount"; "gave one six blows and the other a like number"; "an equal number"; "the same number"
Synonyms: equal, like, same
2.equivalent - being essentially equal to something; "it was as good as gold"; "a wish that was equivalent to a command"; "his statement was tantamount to an admission of guilt"
Synonyms: tantamount

EQUIVALENT. Of the same value. Sometimes a condition must be literally accomplished in forma specifica; but some may be fulfilled by an equivalent, per oequi polens, when such appears to be the intention of the parties; as, I promise to pay you one hundred dollars, and then die, my executor may fulfill my engagement; for it is equivalent to you whether the money be paid to you b me or by him. Roll. Ab. 451; 1 Bouv. Inst. n. 760.
