About the Units

kilogram (kg)

Definition: The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined by the Planck constant since 2019. One kilogram is approximately the mass of one liter of water at 4°C.
History: The kilogram was originally defined in 1795 as the mass of one liter of water. From 1889 to 2019, it was defined by a platinum-iridium cylinder (the International Prototype Kilogram) stored in Paris. The current definition uses fundamental physical constants.
Current use: The kilogram is the global standard for mass. Body weight, food packaging, and cargo are measured in kilograms worldwide. Science and commerce rely on kilograms. The US still uses pounds for everyday weight.

ton (t)

Definition: A ton (t) in the metric system equals 1,000 kilograms. It is also called a metric ton or tonne. The US short ton is 2,000 pounds; the UK long ton is 2,240 pounds.
History: The metric ton was adopted for large-scale commerce and industry. It simplified calculations when dealing with cargo, raw materials, and industrial quantities. The tonne is preferred in international trade.
Current use: Metric tons are used for cargo, shipping, carbon emissions, and industrial production. Vehicle weight and ship displacement use tons. The US sometimes uses short tons for domestic purposes.
