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
