We present the convergence analysis of the cell average technique, introduced in [J. Kumar et al., Powder Technol. 179 (2007) 205–228.], to solve the nonlinear continuous Smoluchowski coagulation equation. It is shown that the technique is second order accurate on uniform grids and first order accurate on non-uniform smooth (geometric) grids. As an essential ingredient, the consistency of the technique is thoroughly discussed.
