Scale is defined as a system or series of marks used for measuring or registering.
The level of measurement is the type of data that is measured. The word scale is sometimes (including in academic literature) used to refer to another composite measure, that of an index. Those concepts are however different. In the social sciences, scaling is the process of measuring or ordering entities with respect to quantitative attributes or traits. For example, a scaling technique might involve estimating individuals' levels of extraversion, or the perceived quality of products. Scientific weight scales are one of the most important instruments in the laboratory.They are used to measure the weight and mass of many different kinds of solids, liquids or powders. Pan Scales. Pan scales are a widely used type of analogue or digital scale. They are easy to transport and are often used for weighing specimens in the field. They are a sturdy type of scale and will stand up to rough handling. Analogue pan scales are fairly accurate and are not susceptible to moisture damage. The definition of a scale is an outer protective layer made up of flat, rigid, overlapping plates. An example of scale is the skin of a fish. Scale is defined as a system or series of marks used for measuring or registering. Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km 1 Scale (map) , the ratio of the distance on a map to the corresponding actual distance. 2  Scale (ratio) , the ratio of the linear dimension of the model to the same dimension of the original. 3  Weighing scale, an instrument used to measure weight.
