Fact about Kilogram
Baci fact: A kilogram [symbol: kg] is the base unit of mass in the SI (International System of Units). It is also known as “kilogramme.” Based on fixed fundamental constants of nature, the kilogram nowadays is defined in terms of the second and the meter. The actual size of the unit remained the same, even though the definition of the kilogram was changed in 2019. Mentioned changes were intended to enhance the definitions of SI base units.
History: The name of this mass unit was derived from the French [kilogramme], which in turn came from adding Greek terminology meaning [a thousand] before the Late Latin term [gramma] that meant “a small weight.”
With an SI prefix, the kilogram is the only SI base unit. SI is a system based on the system of units: meter-kilogram-second rather than a centimeter-gram-second system. This is at least partly due to the lack of coherence and inconsistencies that can occur through the use of centimeter-gram-second systems, like those between the systems of electromagnetic and electrostatic units.
In 1794, the kilogram was initially defined as the mass of one liter of water at its freezing point, though, ultimately defined, since measuring the mass of a volume of water was cumbersome and imprecise.
In 2019, based on Planck’s constant and changes to the definition of the second, a new definition of the kilogram was introduced. Prior to that definition, the kilogram was defined as being equivalent to the mass of a physical prototype, a cylinder made of a platinum-iridium alloy, which was an inadequate measure. The mass of the initial prototype for the kilogram now weighs 50 micrograms less than other copies of the standard kilogram.
Use: The kilogram is used globally in almost all fields and applications, with the exception of countries like the United States, where the kilogram is used in many areas, at least to some degree [such as science, government, industry, and the military] but normally not in everyday applications.
Facts about Gram
Basic facts: A gram is a unit of mass in the SI [International System of Units]. Its symbol is [g]. A kilogram is the base of the definition of a gram, where a gram is one-thousandth of a kilogram, the SI base unit of mass. The definition of the kilogram is no longer based on the international prototype since 2019. It is rather based on Planck’s constant, h, together with the new definitions of the second and the meter.
History: Initially, a gram was defined as the absolute weight of pure water in a cubic centimeter at the temperature of melting ice [later 4 °C]. Until the widespread adoption of SI, which uses kilograms as the base unit of mass, the gram used to be a fundamental unit of mass as part of centimeter-gram-second systems of units. Later, the gram was redefined as one-thousandth of a kilogram, the SI [meter-kilogram-second system of units] base unit of mass.
Use: In every life as well as scientific context, the gram is widely used. For instance, the gram is commonly used to measure non-liquid ingredients used for groceries or cooking. Standards often require the relative contents to be stated per 100 grams of the product on the nutrition labels of food products.
