Scales
A scale (scale, English: weighing scale, scale, scales) is an instrument (tool) that measures the weight and mass of an object. It is a tool for measuring weight and mass, but at the same time it is a tool that can calculate the volume from there if the density is constant. Generally, the scale can be divided into two parts, balance and balance (spring balance), but in the first place "what to measure" is different in the first place. By using the lever and the lever weighing "weight" without being influenced by the magnitude of gravity, the spring balance measures the "weight" by the elongation degree (→ elasticity) of the spring For example. For the difference between weight and mass, refer to mass. ...
