Inspired by Verlinde entropic force interpretation of the Einstein gravity we show that the Brans-Dicke gravity can be also understood as an entropic phenomenon. Due to the variable gravitational coupling in the Brans-Dicke gravity, we have to modify the Unruh-Verlinde temperature in using the equipartition rule. This modified temperature in the Jordan frame is related to the usual Unruh-Verlinde temperature in the Einstein frame via a conformal transformation.
