Ton (Assay) (US) [AT (US)]
The assay ton (AT) is a specialized unit of weight used in the mining and precious metals industries in the United States. It is primarily used to measure ore quantities for assaying, which is the process of analyzing the metal content of ore samples.
One assay ton equals 29.1667 pounds (about 13.23 kilograms), which is different from the standard short ton (2,000 pounds). This smaller ton unit allows for more precise measurements in evaluating the value of ore deposits.
The assay ton helps miners and metallurgists accurately calculate the concentration of valuable metals like gold and silver in ores.
Planck Mass
The Planck mass is a fundamental physical constant in theoretical physics, representing a natural unit of mass based on fundamental constants: the speed of light, gravitational constant, and Planck’s constant.
Its value is approximately 2.18 × 10⁻⁸ kilograms (about 22 micrograms).
The Planck mass is significant in quantum gravity and string theory, marking a scale where quantum effects of gravity become strong and classical physics breaks down.
