Any types of measurement results should be presented with their associated uncertainty. In this post, a method to estimate measurement uncertainties based on Guide to the expression of uncertainty in measurement (GUM) is presented with examples.

In any dimensional and geometrical measurements, different types of measurement error decrease the accuracy of the measurements. These types of measurement error are due to measurement procedures and the structural elements of an instrument

Vernier calliper and micrometre are very common to be used for dimensional measurement. However, many people do not know their fundamental difference.

To understand the importance of measurement uncertainty in practice, we present at least five reasons of why measurement uncertainty estimation has an important role

When we do a measurement, for example a length measurement, it is not correct to only present the measured length.

The fundamental concepts of metrology are revolved around these three aspects: traceability-calibration-uncertainty.
