An electrical counting scale of the type having a sample pan for receiving a known number of pieces of like weight, a commodity receiver for receiving an unknown number of pieces to be counted and a first lever for coupling, in a fixed first ratio, the sample pan to the commodity receiver. The load transducer is coupled to the first lever for generating a load signal representative of a load force thereon, with the load signal being coupled to a load indicating device for displaying a representation thereof. A second lever is coupled between said first lever and said commodity receiver for reducing in a fixed second ratio the primary load force transmitted therebetween. A second commodity receiver is provided for receiving another unknown number of said pieces to be counted. A third lever couples said second commodity receiver to said load transducer for increasing the load force thereon by a fixed third ratio.
