IN CHEMISTRY
Equivalent Weight; Equivalent mass; Gram equivalent; Gram-equivalent weight; Equivalent weight (chemistry)
In chemistry, equivalent weight (also known as gram equivalentgram equivalent Merriam-Webster Dictionary) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.

An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic unit of measurement that was used in chemistry and the biological sciences (see ).

Matrix equivalence

In linear algebra, two rectangular m-by-n matrices A and B are called equivalent if

B = Q 1 A P {\displaystyle B=Q^{-1}AP}

for some invertible n-by-n matrix P and some invertible m-by-m matrix Q. Equivalent matrices represent the same linear transformation V → W under two different choices of a pair of bases of V and W, with P and Q being the change of basis matrices in V and W respectively.

The notion of equivalence should not be confused with that of similarity, which is only defined for square matrices, and is much more restrictive (similar matrices are certainly equivalent, but equivalent square matrices need not be similar). That notion corresponds to matrices representing the same endomorphism V → V under two different choices of a single basis of V, used both for initial vectors and their images.
