Pennyweight (pwt)

The pennyweight (pwt) is a unit of mass traditionally used in the precious metals and jewelry industries. It is part of the troy and apothecary weight systems.

One pennyweight equals 1/20 of a troy ounce, or 24 grains, which is approximately 1.555 grams.

Pennyweights are commonly used to measure gold, silver, and gemstones, offering a precise small-scale weight unit for valuable materials.

Summary:

• 
  

  1 pennyweight = 1/20 troy ounce ≈ 1.555 grams

  
  
• 
  

  Used mainly in precious metals and jewelry

  
  
• 
  

  Part of the troy weight system

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.
