We propose an approach to constructing conservative and invariant differential and difference representations of gas dynamics equations in Lagrangian variables. As shown, a numerical solution may be invariant when a special type of kinetic energy in elementary volume is chosen. Test results are given which illustrate the feasibility of the approach formulated here.
