direktmätning

Direktmätning, meaning direct measurement in Swedish, refers to the process of obtaining a physical quantity’s value by directly comparing it to a standard unit. This contrasts with indirect measurement, where the quantity is determined through calculations involving other measured quantities. In direktmätning, the measuring instrument displays the value of the quantity being measured without requiring any further computation. Examples include using a ruler to measure length, a thermometer to measure temperature, or a voltmeter to measure electrical potential difference. The accuracy of a direktmätning is dependent on the precision of the measuring instrument and the skill of the operator. It is a fundamental concept in metrology and is crucial for ensuring the reliability and consistency of measurements across various scientific and industrial applications. The goal is to achieve a direct and unambiguous representation of the measured value.
