Microgram [µg]


The microgram is a metric unit of mass equal to one-millionth of a gram.



  • 1 microgram = 0.000001 grams = 10⁻⁶ grams



  • 1 microgram = 10⁻⁹ kilograms



  • Symbol: µg (the Greek letter "mu" represents “micro-”)



Key Facts:



  • Commonly used in medicine, pharmacology, and chemistry for very small masses (e.g., drug dosages, contaminants)



  • The prefix "micro-" means 10−610^{-6} (one millionth)



  • Smaller than milligrams, centigrams, and decigrams



The microgram is essential for accurately measuring tiny amounts in scientific and healthcare applications.



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.
