Convert Atomic mass unit [u] to pound-force square second/foot Online | Free weight-and-mass Converter

Atomic Mass Unit [u]

The atomic mass unit (u), also known as the unified atomic mass unit or dalton (Da), is a standard unit of mass used to express atomic and molecular weights.

• 
  

  1 u = 1/12 the mass of a carbon-12 atom

  
  
• 
  

  1 u ≈ 1.66053906660 × 10⁻²⁷ kilograms

  
  
• 
  

  Symbol: u or Da

  
  

Key Facts:

• 
  

  Used to measure the mass of atoms, molecules, and subatomic particles

  
  
• 
  

  1 hydrogen atom ≈ 1 u

  
  
• 
  

  Mass of a proton ≈ 1.007 u, neutron ≈ 1.008 u

  Simplifies comparison of atomic-scale masses in chemistry and physics

  
  

The atomic mass unit provides a convenient and consistent way to express and compare very small masses at the atomic and molecular scale.

It looks like you mentioned "pound-force square second per foot". This is a compound unit that can be broken down into:

• 
  

  pound-force (lbf): a unit of force

  
  
• 
  

  square second (s²): time squared

  
  
• 
  

  per foot (ft⁻¹): per unit length

  
  

What does this unit represent?

It could be a unit for something like mass or inertia-related quantities in imperial units, depending on context. For example, it might show up in equations involving force, time, and length — possibly in mechanics or engineering.

To understand or convert it:

1. 
   

   Pound-force (lbf) is a force unit, where:

   
   

2. 
   

   Second squared (s²) is just time squared.

   
   
3. 
   

   Foot (ft) is length:
