Grams (g)
Definition
A gram (g) is a metric unit of mass equal to one thousandth of a kilogram. It was originally defined as the mass of one cubic centimeter of water at 4°C.
History
The gram was introduced in 1795 as the base unit of mass in the original metric system. Though the kilogram later replaced it as the SI base unit, the gram remains the most commonly used unit for everyday small-scale measurements.
Current use
Grams are used worldwide for food labeling, cooking recipes, postal weighing, jewelry and gemstone measurement, and small-scale scientific work. Nutritional information on food packaging is universally expressed in grams.
Kilograms (kg)
Definition
A kilogram (kg) is the SI base unit of mass, equal to 1,000 grams. Since 2019, it is defined by the Planck constant rather than a physical artifact.
History
The kilogram was established in 1795 during the French Revolution as the mass of one liter of water. From 1889 to 2019, it was defined by the International Prototype of the Kilogram (a platinum-iridium cylinder in Paris). The 2019 redefinition linked it to the Planck constant for improved precision.
Current use
Kilograms are the universal standard for body weight, grocery products, luggage allowances, industrial materials, and scientific measurements. It is the base unit of mass in all scientific and most commercial contexts worldwide.
