There is a need for the measurements of the lengths, distances, weights, heights, volumes, etc., of several objects in our everyday life. One of the most important aspects of measuring is selecting proper units and techniques for the accurate measurements of these physical quantities.  In physics, the measurements of different physical quantities are done correctly […]

Gauge pressure is the pressure of a system that is greater than the surrounding atmosphere. Due to the fact that gauge pressure is zero-referenced against atmospheric pressure, gauge pressure readings include pressure due to atmospheric weight as well as pressure due to ambient air (or atmospheric). This means that gauge pressure varies depending on the

Introduction  Let’s look at the Fundamental and Derived Units:  Fundamental and Derived Units   Physics is a discipline of science concerned with the study of nature and natural events, as we all know. Let’s assume I drop a ball from a specific height and it lands on the ground freely. To acquire an exact response to

SI units are highly commonly used standards of measurement worldwide when it comes to measuring weight, length, mass and temperature. While new standards of measurement have come into place over the years, SI units have incorporated these new standards under their ambit. What are fundamental and derived units? They are used just about everywhere and

We have several different units in science and engineering to measure the range of objects‘ physical quantities. We measure qualities in real-world scenarios and discover and define the fundamental characteristics of various things, such as height, weight, and length. We use a system of units known as the SI system in the modern world. Physical

Ever wondered why the edges of a knife are made sharp, why the nails that we use are made pointed. The answer to all these questions is based on the concept of pressure. It is generally defined as the amount of force applied to a certain area. It is a physical quantity. Its formula can

Every physical quantity is measured by comparing it to a fundamental, arbitrarily chosen, internationally agreed on reference standard known as a unit. A physical quantity measurement is stated as a number (or numerical measure) followed by a unit that is further calculated by dimensional formula. Even though the number of physical quantities appears to be

If you are looking to examine the Seven Base SI Units, you are at the correct place. Read out the entire article to know about the SI units and how often they are used.  The various individual units (e.g., expressed in power, kilos, pounds, etc.) and the systems of the units have made possible the

Previously, scientists from various countries used different measurement methods. Until recently, three such systems, the CGS, the FPS (or British) system, and the MKS system, were widely used. The following were the basic units for length, mass, and time in these systems: In the CGS system, they were centimetre, gram, and second;  In the FPS

Introduction Measurement is the muse of all experimental science. In an experiment, we may get a different value than the true value due to either faulty equipment, carelessness, or other reasons. This causes an error in measurement. The result of each measurement by any measuring device contains some uncertainty. This uncertainty is called an error.
