KILOGRAM Meaning and
Definition
-
A kilogram is a unit of measurement used for measuring mass in the International System of Units (SI). It is denoted by the symbol "kg" and is defined as the base unit of mass. The kilogram is commonly used all over the world to measure the mass of objects and substances.
Historically, the kilogram was defined as the mass of a specific platinum-iridium alloy cylinder known as the International Prototype of the Kilogram (IPK), which was stored at the International Bureau of Weights and Measures (BIPM) in France. However, in recent years, the definition of the kilogram has been revised.
As of 2019, the kilogram is defined using the Planck constant, a fundamental constant in physics. The current definition states that the kilogram is equal to the mass of a particular quantity of photons (particles of light) with a certain energy, as determined by the Planck constant.
The kilogram is one of the seven SI base units and is used in a wide range of scientific and everyday applications. It is important in fields such as physics, engineering, chemistry, and commerce. The kilogram plays a central role in calculations involving force, inertia, weight, and other aspects of mechanics and physical sciences.
In summary, the kilogram is a unit of measurement used to quantify mass, defined as the base unit of mass in the SI system. It is widely used across various disciplines for measuring the mass of objects and substances.

Etymology of KILOGRAM
The word "kilogram" is derived from two Greek words: "kilo", meaning "a thousand", and "gramma", meaning "a small weight". The term was coined in the late 18th century as part of the French metric system. Initially, the kilogram was defined as the weight of one liter of water at its freezing point, but it was later redefined based on a physical artifact known as the International Prototype of the Kilogram (IPK). However, the definition of the kilogram was recently changed in 2019, shifting from the IPK to a fundamental constant of nature known as the Planck constant.
