Kilogram

Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is equal to 1000 grams.

History/origin: The kilogram was originally defined as the mass of a specific artifact called the International Prototype Kilogram (IPK), a platinum-iridium cylinder. In 2019, the definition was redefined based on fundamental physical constants.

Current use: Kilograms are used for measuring the mass of larger objects, such as people, packages, and vehicles. It's a standard unit in commerce, engineering, and science.

Gram

Definition: A gram (symbol: g) is a unit of mass in the metric system. It was originally defined as the mass of one cubic centimeter of pure water at the temperature of maximum density.

History/origin: The gram is the base unit of mass in the metric system, which was established in France in the late 18th century. It was intended to be a universal and rational system of measurement.

Current use: Grams are widely used for measuring the mass of food items, ingredients, and small objects. It's a standard unit in cooking, chemistry, and various industries.
