In measure theory, a conull set is a set whose complement is null, i.e., the measure of the complement is zero.[1] For example, the set of irrational numbers is a conull subset of the real line with Lebesgue measure.[2]

A property that is true of the elements of a conull set is said to be true almost everywhere.[3]
