We propose an inverse method to extract effective couplings and the renormalization group flow for macroscopic dynamical systems. We applied it to discrete surface growth models in the Kardar-Parisi-Zhang universality class in 1+1 dimensions and obtain the first measurement of a universal coupling constant. It may also be applicable to analyze experimental data such as immiscible fluid displacement experiments.
