Kilogramo
Definición: Un kilogramo (símbolo: kg) es la unidad base de masa en el Sistema Internacional de Unidades (SI). Actualmente se define en base al valor numérico fijo de la constante de Planck, h, que es igual a 6.62607015 × 10 -34 en las unidades de J·s, o kg·m 2 ·s -1 . El metro y el segundo se definen en términos de c, la velocidad de la luz y la frecuencia del cesio, Δ ν Cs. Aunque la definición de kilogramo cambió en 2019, el tamaño real de la unidad sigue siendo el mismo. Los cambios estaban destinados a mejorar las definiciones de las unidades básicas del SI, no a cambiar realmente la forma en que se utilizan las unidades en todo el mundo.
Historia/origen: El nombre kilogramo se derivó del francés "kilogramme", que a su vez provino de agregar la terminología griega que significa "mil", antes del término latino tardío "gramma" que significa "un peso pequeño".
A diferencia de las otras unidades base SI, el kilogramo es la única unidad base SI con un prefijo SI. SI es un sistema basado en el sistema de unidades metro-kilogramo-segundo en lugar de un sistema centímetro-gramo-segundo. Esto se debe, al menos en parte, a las inconsistencias y la falta de coherencia que pueden surgir mediante el uso de sistemas centímetro-gramo-segundo, como los que existen entre los sistemas de unidades electrostáticas y electromagnéticas.
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.
Pound
Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The avoirdupois pound is equivalent to 16 avoirdupois ounces.
History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the 13th century. It was updated to its current form in 1959. It is a system that was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.
Current use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.
