The consistency of an electronic scale to measure substances is known as what?

The term that describes the consistency of an electronic scale in measuring substances is precision. Precision refers to the degree to which repeated measurements under unchanged conditions provide the same results. In this context, an electronic scale can consistently measure the weight of the same substance multiple times, producing very similar or identical results, which is a reflection of its precision.

While accuracy refers to how close a measured value is to the actual (true) value, precision focuses solely on the reproducibility of measurements regardless of their accuracy. Repeatability, which is also mentioned, is closely related and emphasizes the ability to obtain the same measurement when repeating the process under the same conditions. Reliability, on the other hand, generally refers to the overall consistency and trustworthiness of a measurement instrument. In this case, precision is the most appropriate term to describe the consistency of the scale's measurements.
