Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
Earth's Mass
Earth's mass (M_earth) is a unit of mass representing the mass of the Earth, approximately 5.972 × 10^24 kilograms.
History/Origin
The concept of Earth's mass as a unit originated from scientific measurements of Earth's size and gravitational influence, becoming a standard reference in geophysics and astronomy.
Current Use
M_earth is used in scientific contexts to express planetary and astronomical masses, and in some cases, to compare the mass of other celestial bodies relative to Earth.
