Onza
Definición: Una onza (símbolo: oz) es una unidad de masa en los sistemas de medición imperial y estadounidense. La onza avoirdupois (la onza común) se define exactamente como 28,349523125 gramos y equivale a un dieciseisavo de una libra avoirdupois.
Historia/origen: El origen del término onza proviene de la uncia romana, que significa "doceava parte", y el uso de una barra de cobre estandarizada que definía tanto la libra romana como el pie. La barra de cobre se dividía en doce partes iguales, llamadas unciae. Esta relación entre la libra romana y el pie finalmente contribuyó a que la uncia fuera la base de la pulgada moderna, así como de la onza común. La onza se ha utilizado como patrón de masa a lo largo de la historia para diferentes aplicaciones y con diferentes definiciones. Los ejemplos incluyen la onza métrica holandesa (100 g), la onza francesa (30,59 g) y la onza española (28,75 g), entre otros. La definición actual de la onza, la onza internacional avoirdupois, se adoptó en 1959.
Uso actual: La onza sigue siendo una unidad de masa estándar en el sistema de medición habitual de EE. UU. Se utiliza principalmente en los Estados Unidos para medir productos alimenticios envasados, porciones de alimentos y artículos postales, entre otras cosas. La onza todavía se usa en algunos otros países del mundo que tienen raíces en la historia y la cultura británicas. Debido a la métrica, el Reino Unido (UK) ya no usa oficialmente la onza. Sin embargo, todavía se usa en algunos lugares del Reino Unido, como los restaurantes.
Kilogramo
Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is currently defined based on the fixed numerical value of the Planck constant, h, which is equal to 6.62607015 × 10-34 in the units of J·s, or kg·m2·s-1. The meter and the second are defined in terms of c, the speed of light, and cesium frequency, ΔνCs. Even though the definition of the kilogram was changed in 2019, the actual size of the unit remained the same. The changes were intended to improve the definitions of SI base units, not to actually change how the units are used throughout the world.
History/origin: The name kilogram was derived from the French "kilogramme," which in turn came from adding Greek terminology meaning "a thousand," before the Late Latin term "gramma" meaning "a small weight."
Unlike the other SI base units, the kilogram is the only SI base unit with an SI prefix. SI is a system based on the meter-kilogram-second system of units rather than a centimeter-gram-second system. This is at least in part due to the inconsistencies and lack of coherence that can arise through use of centimeter-gram-second systems, such as those between the systems of electrostatic and electromagnetic units.
The kilogram was originally defined as the mass of one liter of water at its freezing point in 1794, but was eventually re-defined, since measuring the mass of a volume of water was imprecise and cumbersome.
A new definition of the kilogram was introduced in 2019 based on Planck's constant and changes to the definition of the second. Prior to the current definition, the kilogram was defined as being equal to the mass of a physical prototype, a cylinder made of a platinum-iridium alloy, which was an imperfect measure. This is evidenced by the fact that the mass of the original prototype for the kilogram now weighs 50 micrograms less than other copies of the standard kilogram.
Current use: As a base unit of SI, the kilogram is used globally in nearly 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 extent (such as science, industry, government, and the military) but typically not in everyday applications.
