Because lead uses 11.33 grams per cc and that is very accurate more accurate then any other metal i think. (Check this on some other website). I Recommend Britannca

Lead is used for weights and scales due to its high density, making it efficient for achieving precision in measurements. It is also readily available, malleable, and resistant to corrosion, making it a practical choice for these applications.
True. Balance scales are used to measure the mass of an object by comparing it to known weights on the other side of the scale until balance is achieved.
Calibration weights are used to verify the accuracy and precision of weighing scales. By using known reference weights, the scale can be adjusted to ensure it is measuring correctly. Calibration ensures that measurements are reliable and traceable.
Lead is commonly used to make objects such as batteries, radiation shielding, bullets, and fishing weights.
Slotted weights are used for calibrating and testing weighing scales by adjusting the weight on the scale. They are commonly used in physics experiments to demonstrate principles of mass and weight. Slotted weights can be easily added or removed from a hanger or balance to achieve the desired weight for an experiment or calibration.
Scales work as a lever by balancing the weight of an object on one end with standard weights on the other end. As the object exerts a force downwards, the lever arm moves, causing the standard weights to move as well until equilibrium is reached. The position of the standard weights then gives an indication of the object's weight.
