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.

Dalton (Da)

The dalton, symbolized as Da, is a unit of mass used to express atomic and molecular masses.

• 
  

  It is equivalent to the unified atomic mass unit (u).

  
  
• 
  

  1 dalton = 1/12 the mass of a carbon-12 atom ≈ 1.66054 × 10⁻²⁷ kilograms

  
  
• 
  

  Commonly used in chemistry, biochemistry, and molecular biology to measure the mass of atoms, molecules, and proteins.

  
  

Key Facts:

• 
  

  1 Da ≈ mass of one nucleon (proton or neutron)

  
  
• 
  

  Used to describe molecular weights (e.g., a protein might be 50,000 Da)

  
  
• 
  

  Helps standardize measurements on atomic and molecular scales

  
  

The dalton provides a convenient, standardized scale for describing the masses of tiny particles in science.
