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.

Kilogram (kg)

The kilogram is the SI base unit of mass, representing the amount of matter in an object.

• 
  

  It is symbolized as kg.

  
  
• 
  

  Since 2019, the kilogram is defined by fixing the value of the Planck constant to exactly $6.62607015 \times 10^{-34}$ joule seconds, linking mass to fundamental physical constants.

  
  
• 
  

  Before this, it was defined by a physical platinum-iridium prototype.

  
  
• 
  

  It is the only SI base unit still using the prefix "kilo" in its name.

  
  

Key points:

• 
  

  1 kg is the base unit of mass in the metric system

  
  
• 
  

  Defined using the Planck constant for high precision

  
  
• 
  

  Widely used globally in science, industry, and everyday life

  
  

The kilogram ensures accurate and universal mass measurements across the world.
