Abstract: It is shown that nonlinear operators which preserve the integral are order preserving if and only if they are nonexpansive in $ {L^1}$ and that those which commute with translation by a constant are order preserving if and only if they are nonexpansive in $ {L^\infty }$. Examples are presented involving partial differential equations, difference approximations and rearrangements.
