Pennyweight unit

The pennyweight (dwt) is a traditional unit of mass commonly used in the measurement of precious metals such as gold, silver, and platinum. One pennyweight is equivalent to 1/20th of a troy ounce, or approximately 1.555 grams. This unit is often utilized by jewelers and in the bullion trade to express the weight of small quantities of metals with precision. Understanding the pennyweight is essential for anyone involved in buying, selling, or appraising fine jewelry and precious metal commodities.
