Gramo
Definición: Un gramo (símbolo: g) es una unidad de masa en el Sistema Internacional de Unidades (SI). La definición del gramo se basa en el kilogramo, donde un gramo es una milésima parte de un kilogramo, la unidad de masa base del SI. Desde 2019, la definición del kilogramo ya no se basa en el prototipo internacional, sino en la constante de Planck, h, junto con las nuevas definiciones del segundo y el metro.
Historia/origen: Originalmente, un gramo se definió como el peso absoluto de agua pura en un centímetro cúbico a la temperatura de fusión del hielo (luego 4 °C). El gramo solía ser una unidad fundamental de masa como parte de los sistemas de unidades centímetro-gramo-segundo hasta la adopción generalizada del SI, que utiliza kilogramos como unidad de masa base. El gramo se redefinió más tarde como una milésima parte de un kilogramo, la unidad base de masa SI (sistema de unidades metro-kilogramo-segundo).
Uso actual: el gramo se usa ampliamente en la vida cotidiana, así como en contextos científicos. Por ejemplo, el gramo se usa típicamente para medir ingredientes no líquidos que se usan para cocinar o hacer comestibles. Las normas sobre las etiquetas de información nutricional de los productos alimenticios a menudo exigen que se indique el contenido relativo por cada 100 gramos del producto.
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.

How to Convert Gram to Kilogram
1 g = 0.001 kg
1 kg = 1000 g
Example: convert 15 g to kg:
15 g = 15 × 0.001 kg = 0.015 kg
