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.
Solar MassM☉
Target UnitThe solar mass (M☉) is a unit of mass used in astronomy to describe the mass of celestial objects in relation to the Sun. Defined as approximately 1.989 × 10^30 kilograms, it serves as a convenient benchmark for the masses of stars, galaxies, and other astronomical bodies. Since the Sun is the most massive object in our solar system, the solar mass is a natural and practical unit for comparing stellar masses, allowing astronomers to express the mass of other stars in terms of how many times they are more or less massive than the Sun.
Current Use
Today, the solar mass is widely used in various fields of astronomy and astrophysics. It is crucial for calculating the gravitational interactions between celestial bodies, allowing astronomers to determine the orbits of planets, moons, and other objects in space. Additionally, it is employed in the modeling of stellar evolution, assessing how stars of different masses evolve over time. The solar mass is also used in the classification of stars and the study of galaxy dynamics.
Fun Fact
The Sun contains about 99.86% of the total mass of the solar system.

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 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 solar mass (M☉) is a unit of mass used in astronomy to describe the mass of celestial objects in relation to the Sun. Defined as approximately 1.989 × 10^30 kilograms, it serves as a convenient benchmark for the masses of stars, galaxies, and other astronomical bodies. Since the Sun is the most massive object in our solar system, the solar mass is a natural and practical unit for comparing stellar masses, allowing astronomers to express the mass of other stars in terms of how many times they are more or less massive than the Sun.
History & Origin
The concept of using the Sun's mass as a standard originated in the early 20th century as astronomers sought a reliable reference for stellar mass. Prior to this, various methods were used to estimate masses of celestial bodies, often leading to inconsistencies. The solar mass was proposed as a universal standard, enabling astronomers to compare different stars and galaxies more easily. This standardization was crucial in the development of stellar dynamics and the understanding of the universe's structure.
Etymology: The term 'solar' derives from the Latin word 'solaris', which means 'of the sun'. Hence, 'solar mass' literally refers to the mass associated with the Sun.
