In abstract algebra, the transcendence degree of a field extension L / K is a certain rather coarse measure of the "size" of the extension. Specifically, it is defined as the largest cardinality of an algebraically independent subset of L over K. If no field K is specified, the transcendence degree of a field L is its degree relative to the prime field of the same characteristic, i.e., the rational numbers field Q if L is of characteristic 0 and the finite field Fp if L is of characteristic p.
