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.

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.
