Poundal (pdl)

The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system of measurement. It is defined as the force required to accelerate a one-pound mass by one foot per second squared. In other words,

1 poundal = 1 lb × 1 ft/s².

The poundal is much smaller than the more commonly used pound-force (lbf). It’s mainly used in some engineering contexts and classical mechanics problems where the FPS system is preferred. However, it is less common than the SI unit of force, the newton.

Conversion:

1 poundal ≈ 0.13825 newtons.

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.
