In a recent simulation, Biskamp and Welter (Phys. Fluids B {bold 1}, 1964 (1989)) noted that the dissipation scale in two-dimensional magnetohydrodynamic turbulence appears to be {ital l}{sub {ital d}}=({ital l}{sup 2}{sub K}{lambda}){sup 1/3}, where {ital l}{sub K} is the Kolmogorov dissipation scale and {lambda} the Taylor microscale. Here, it is shown that this result can be obtained from a simple scaling argument, and is not a consequence of intermittency.
