Pennyweight: The pennyweight (abbreviated as dwt) is a unit of mass commonly used in the jewelry industry to measure the weight of precious metals, particularly gold and silver. One pennyweight is equal to 24 grains or approximately 1.555 grams.
A centigram (cg) is a metric unit of mass or weight in the International System of Units (SI). It represents one one-hundredth of a gram or 10^-2 grams. The metric system is a decimal-based system of measurement used worldwide, and it provides a convenient way to express both large and small quantities of mass.
To provide context for the size of a centigram:
Centigrams are primarily used in situations where very small amounts of mass need to be measured with precision. However, they are not as commonly used as milligrams (10^-3 grams) or micrograms (10^-6 grams) in scientific and laboratory contexts. In everyday life, you may encounter centigrams less frequently, but they are still a valid metric unit of mass.
