Abstract
Metrology is known to be a science of measurement and its application. Measurement is carried out by indicating measuring instruments, transducers, material measures, comparators and other measuring devices. Quality of many modern measuring devices is based often on characteristics of analog integrated circuits. Mathematical modelling of measurement (including the evaluation of a measurement uncertainty) is very important. Measuring devices and modelling can be described by the conversion of input quantities to an output quantity. All possible quantities can be divided into two parts: physical and mathematical quantities. General approach to the evaluation of uncertainty for the all kinds of conversions is offered in this paper.
