Unit Explanations
Kilogramkg
Source UnitThe kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. This definition was established in 1889 and was the only base unit defined by a physical object. However, in 2019, the definition of the kilogram was redefined in terms of fundamental constants, specifically the Planck constant (h), which is set at exactly 6.62607015 × 10^-34 joule seconds. This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
Current Use
Today, the kilogram is widely used across the globe as the standard unit of mass in scientific, commercial, and everyday contexts. It is employed in various industries including manufacturing, agriculture, and healthcare. For instance, in the food industry, products are often sold by mass, measured in kilograms. In healthcare, medication dosages may also be prescribed based on the patient’s weight in kilograms. While most countries use the kilogram as part of the metric system, some countries, such as the United States, still use imperial units for certain applications, though the metric system is increasingly adopted in scientific and technical fields. The versatility of the kilogram makes it a vital unit in international trade and commerce.
Fun Fact
The kilogram was the first unit of measurement to be defined by a physical artifact.
Neutron Massm_n
Target UnitThe neutron mass is a fundamental property of the neutron, a subatomic particle found in the nucleus of atoms. It is approximately 1.675 x 10^-27 kilograms (kg), which is about 1,839 times the mass of an electron. Neutrons are electrically neutral and play a crucial role in the stability of atomic nuclei. The mass of the neutron is an important parameter in nuclear physics, influencing nuclear reactions and the behavior of atoms. In energy terms, the mass-energy equivalence principle, given by E=mc², indicates the energy equivalent of the neutron's mass.
Current Use
Today, the neutron mass is crucial in various areas of science and technology. In nuclear physics, it is used to predict the behavior of nuclear reactions, such as fission and fusion. Neutrons are also employed in neutron scattering experiments, which are essential for studying the structure of materials in condensed matter physics. Additionally, the measurement of neutron mass underpins calculations in nuclear medicine, particularly in therapies involving radioisotopes. This unit is significant in high-energy physics and astrophysics research as well.
Fun Fact
Neutrons are responsible for most of the mass of an atom despite being neutral particles.

Definition
The kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. This definition was established in 1889 and was the only base unit defined by a physical object.

This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
History & Origin
The kilogram originated in the late 18th century during the period of the French Revolution, as part of the efforts to standardize measurements across France and eventually the world. The need for a uniform measurement system became apparent in the wake of the Revolution, as varying local measures were causing confusion and inefficiency in trade and governance. Thus, the metric system was born, with the kilogram being one of its foundational units. The first kilogram was defined as the mass of one liter of water at its maximum density, which is approximately equal to 1,000 cubic centimeters. This practical approach to defining mass allowed for easier adoption across various sectors.
Etymology: The term 'kilogram' is derived from the Greek word 'kilo', meaning 'a thousand', and the French word 'gramme', which itself comes from the Late Latin 'gramma', meaning 'small weight'.

Definition
The neutron mass is a fundamental property of the neutron, a subatomic particle found in the nucleus of atoms. It is approximately 1.675 x 10^-27 kilograms (kg), which is about 1,839 times the mass of an electron. Neutrons are electrically neutral and play a crucial role in the stability of atomic nuclei. The mass of the neutron is an important parameter in nuclear physics, influencing nuclear reactions and the behavior of atoms. In energy terms, the mass-energy equivalence principle, given by E=mc², indicates the energy equivalent of the neutron's mass.
History & Origin
The concept of the neutron was first proposed by Ernest Rutherford in 1920, but it wasn't until 1932 that James Chadwick experimentally confirmed its existence. He discovered the neutron while conducting experiments with alpha particles and beryllium, leading to the identification of a neutral particle that would later be termed the neutron. This discovery was pivotal in the development of nuclear physics and provided a deeper understanding of atomic structure, directly impacting theories of nuclear reactions and the development of nuclear energy.
Etymology: The word 'neutron' is derived from the Latin root 'neutralis', meaning 'neutral', reflecting its lack of electric charge.
