M.K.S, F.P.S and C.G.S. Systems Of Units.

A system of units is a collective list of units used to measure any item. Units are essential to understanding the measured value of a quantity. These units are used to relate and observe the measurement of any item, thereby understanding the magnitude of the quantity better. Length, mass and second are primary quantities that […]

Length, Mass, Time, and Measurements

Introduction:  Measuring is essentially a process of comparison. To determine how many times a standard amount of a physical quantity is present in the quantity being measured, we must first determine how many times a known standard amount of the physical quantity appears in the quantity being measured. The magnitude of the physical quantity is

Length, Mass and Time Measurements

Measurements are discovered to increase the knowledge and understanding of segregating materials. The law of physics is reflected in terms of physical quantities. The measurements should have a standardised unit that is common worldwide. Length, mass and time are the three main and basic quantities in measurement. These three units of measurement form the mks

Key Note on Systems of Units

A unit system is a collection of units related to each other that are utilised for calculation. The system comprises base units, which are base dimensions, and derivation units. Specific units are part of multiple systems of units. In the MKS (metre, kilogram and second) model, the three base units are the metre, kilogram and

Interpretation About The Need For Measurement

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

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

fundamental and derived units

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

Fundamental and Derived SI Units

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

Excess of pressure

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
