Picogram
A picogram (pg) is a unit of mass equal to one trillionth (10^-12) of a gram.
History/Origin
The picogram was introduced as part of the metric system to measure extremely small masses, especially in scientific and laboratory contexts, as a subdivision of the gram in the SI unit system.
Current Use
Picograms are used in scientific fields such as biology, chemistry, and physics to measure very small quantities of substances, including DNA, proteins, and other microscopic materials.
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.
