What is a carat?
A metric carat is a unit of mass used to measure gemstones and pearls. One carat is equivalent to 200 milligrams or 0.2 grams. This unit is commonly used in the jewelry industry to determine the weight of precious stones such as diamonds, sapphires, and rubies. The carat weight of a gemstone is a crucial factor in determining its value and is often used in conjunction with other factors such as cut, color, and clarity to assess its overall quality.
What is a long ton (imperial ton)?
A long ton, also known as an imperial ton, is a unit of weight commonly used in the United Kingdom and some other Commonwealth countries.
It is equivalent to 2,240 pounds or 1,016 kilograms. The long ton is primarily used in the context of trading goods, particularly in industries such as shipping, agriculture, and mining.
In terms of metric conversions, a long ton is equal to approximately 1.016 metric tonnes. This means that one long ton is slightly heavier than one metric ton, which is equivalent to 1,000 kilograms. The long ton is not commonly used in countries that have adopted the metric system, but it is still relevant in certain industries and historical contexts where imperial units are preferred.
