Convert micrometers (microns) to decimeters, um to dm

 

Let's consider about measurement devices. Although, it is not related closely to the converter of microns to decimeters.

In the literature and in some regulatory documents of the past years, you can find the following definition of the term measuring device: "a technical device intended for measurements, having standardized metrological characteristics, reproducing and (or) storing a unit of a physical quantity, the size of which is taken as unchanged (within the established error) during a known interval time".

 

The point is that indeed, in its essence, any technical means (adjustment) using which measurements are used is a means of measurement. In the first formulation, a private case of measuring instruments of the approved type is described, with mandatory requirements established for them, mostly aimed at application in the sphere of state regulation. 

 

Means of measurement must be tested to approve the type; mandatory metrological requirements must be established for them.

Measurement instruments must be certified and recognized as suitable for use. Measurement instruments used outside the scope of state regulation may be subject to voluntary verification or calibration.

 

An exceptional category of measurement instruments is known as technical devices with measuring processes. These are systems and devices that perform measurement tasks in addition to serving their primary functions. Such devices include complex systems where measurement is not the main purpose.
