Weighing apparatus of the platform scale type, characterized by the provision of load lever means including a pair of parallel load levers of unequal lengths for transmitting the vertical movement of the platform to weighing means mounted on one side thereof. Each load lever is connected at a first end with the frame of the apparatus, the other ends of the levers being connected with the weighing means. The load force of the platform is applied to an intermediate point on each of the levers adjacent their first ends, the ratio of the distance between said intermediate point and said first lever end to the distance between the intermediate point and the other lever end being the same for each lever. Preferably the said other ends of the load levers are connected with the weighing means by means including a pair of knife edges having a common horizontal line normal to the lever axes, the first ends of the levers extending under the platform means.
