A grinding-dosing machine with a dosing device for ground coffee, adapted to be fixed to a coffee grinder to form a grinding-dosing machine, comprises a main body, having a dispensing conduit which is configured to receive ground coffee from a coffee grinding device, and discharge it by gravity into a filter holder, and a closure element which can close the conduit and allow ground coffee to build up in the conduit. A bending beam load cell has a first end portion connected to the main body and a second end portion attached to the coffee grinding device. Thus the load cell will support the main body which hangs therefrom, and measure the weight of the ground coffee built up in the conduit.
