Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
Tonne
A tonne (symbol: t) is a metric unit of mass equal to 1,000 kilograms or approximately 2,204.62 pounds.
History/Origin
The tonne was introduced as part of the metric system in the 19th century to standardize measurements of mass globally, replacing various local units with a single, consistent unit.
Current Use
The tonne is widely used internationally in industries such as shipping, manufacturing, and agriculture for measuring large quantities of materials and commodities.
