In Metrology The least count of an instrument is the smallest change in the value that can be measured with the measuring instrument. Least count for Steel Ruler For example in a Steel Ruler, there are twenty divisions between each 10-millimetre scale reading. So the least count for this steel ruler is 0.5 millimetre. The formula for […]
Metrology is a science of measurement. It meant to understand the units of each quantity and the realisation of the units and calibration. In each country, they follow different unit systems, among them, the Metric system is the predominant system in the world. In this article, we have listed all the different Metrology topics that we have discussed so far.
Based upon the field of application Metrology can be further divided into
- Industrial metrology
- Scientific or Fundamental metrology
- Legal metrology
see what are these different metrology types here.
Topic: What are the different vernier caliper types? Vernier calliper is a device used to measure the dimensions of the workpiece with high accuracy and precision. The construction and working principle of vernier caliper is explained here Vernier Caliper Types According to Indian standards, there are three vernier caliper types. The first one is with jaws on […]
Topic: Measurement systems | System of Measurements The basic fundamental Units in the system of measurements are Length, Time, Mass, Temperature etc. All the physical quantities can be expressed in terms of these fundamental units. The Different system of measurements can be used in different countries are discussed in the following video. If you like to read the […]
Metrology is a science of measurements. We have discussed what are the different Linear measuring instruments. Vernier scale is a precise measuring instrument, Comparatively low accuracy than the other precision measuring instruments. The different types Vernier callipers are available to measure internal, external measurements. In this article, we are going to discuss the Vernier Calliper Diagram, Working […]
Topic: What is Linear Measurement? In Metrology, Linear measurement applies to the measurement of lengths, diameters, heights and thickness including external and internal measurements. Instruments used for Linear Measurement: Linear measurement instruments can be classified into Direct and indirect measuring instruments. Direct measuring instruments. Graduated Measuring instruments Non Graduated measuring instruments Indirect measuring instruments. They can be further […]
