Pennyweight
The pennyweight (pwt) is a unit of weight traditionally used in measuring precious metals and gemstones, equivalent to 1/20 of a troy ounce or 1.555 grams.
History/Origin
Originating in the medieval period, the pennyweight was used in the troy weight system for weighing gold and silver, especially in the jewelry and precious metals industries. Its use has persisted in certain regions and industries for historical and practical reasons.
Current Use
Today, the pennyweight is primarily used in the jewelry trade and precious metals markets to specify weights of gold, silver, and gemstones, especially in the United States and in contexts where precise measurement of small quantities is required.
Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
