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 Ounce
Basic facts: An ounce is a unit of mass in the US customary and imperial systems of measurement. Its symbol is [oz]. The avoirdupois ounce, which is the common ounce, is defined as precisely 28.349523125 grams and is equal to one-sixteenth of an avoirdupois pound.
History: The term ounce originates from the Roman uncia, which means a [twelfth part] and the use of a standardized copper bar which defined the Roman pound as well as the foot. The copper bar was divided into twelve identical parts, called unciae. This relationship between the Roman pound and foot ultimately contributed to the uncia being the basis of both the modern inch and the common ounce. Throughout history, the ounce has been used as a standard of mass for various applications and with different definitions. Examples include the French ounce (30.59g), Spanish ounce (28.75g), and the Dutch metric ounce (100g) among others. In 1959, the current definition of the ounce, the international avoirdupois ounce was adopted.
Use: In the US customary system of measurement, an ounce is still a standard unit of mass. It is mainly used in the United States for food portions, measuring packaged food products, and postal items, among other things. In some other countries around the world that have roots in British history and culture, the ounce is still used. The United Kingdom no longer officially uses the ounce due to metrication. It is, however, still used in some settings (restaurants) in the United Kingdom.
