What are pennyweights?
Pennyweights are a unit of measurement commonly used in the jewelry industry to measure the weight of precious metals such as gold and silver.
One pennyweight is equivalent to 1/20th of a troy ounce, which is approximately 1.555 grams. This unit is particularly useful for measuring small quantities of precious metals with high precision, making it a popular choice among jewelers and goldsmiths.
In the metric system, pennyweights are not commonly used, as the system primarily relies on units such as grams and kilograms for measuring weight. However, for those who work with precious metals and gemstones, understanding the conversion between pennyweights and metric units can be important for accurate measurements and transactions
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.
