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 hundredweight?
A long hundredweight, also known as the imperial hundredweight, is a unit of weight commonly used in the United Kingdom and other countries that follow the imperial system of measurements.
It is equivalent to 112 pounds or approximately 50.802 kilograms. The long hundredweight is often used in trade and commerce for measuring bulk goods such as grains, coal, and other commodities.
In the metric system, the equivalent unit of weight to a long hundredweight is the metric ton, also known as a tonne. One metric ton is equal to 1,000 kilograms or approximately 2,204.62 pounds. When converting from long hundredweights to metric tons, one would divide the weight in long hundredweights by 20 to obtain the weight in metric tons. For example, if a shipment weighs 5 long hundredweights, it would be equivalent to 0.25 metric tons. The metric ton is the preferred unit of weight in most countries around the world due to its simplicity and ease of conversion in the metric system.
