Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
Kiloton (Metric)
A kiloton (kt) is a unit of mass equal to 1,000 metric tons or 1,000,000 kilograms.
History/Origin
The term 'kiloton' originated in the 20th century, primarily used in military and scientific contexts to measure large quantities of explosive energy or mass, especially in nuclear weapon yields and large-scale industrial measurements.
Current Use
Today, kilotons are commonly used to express the explosive yield of nuclear weapons, the mass of large objects, and in scientific research related to energy and mass measurements.
