Common weight units

Gram (g)

Definition: A gram (symbol: g) is one thousandth of a kilogram (1 g = 0.001 kg). It is a unit of mass in the SI metric system and the most practical unit for measuring small quantities.

History/origin: The gram was originally defined in 1795 as the mass of one cubic centimeter of water at 4 °C, the same basis as the early kilogram definition, just scaled down by a factor of 1,000.

Current use: Grams are widely used in food nutrition labels, cooking recipes, pharmaceutical doses, and jewellery. Most food packaging worldwide lists weight in grams or kilograms.

Metric ton (t)

Definition: The metric ton, or tonne, is a large metric mass unit. One t equals 1,000 kg, or one million grams.

History/origin: Metric trade needed a unit larger than the kilogram for bulk goods, and the tonne provided a decimal-friendly measure for heavy loads.

Current use: T is common in freight, grain markets, steel production, carbon emissions, vehicle weights, mining output, livestock feed, and international shipping.
