What is Pound-Force (lbf)?

pound-force (lbf) is a unit of force in the imperial system. It represents the force exerted by gravity on a one-pound mass at Earth’s surface.

Key Facts About Pounds-Force

  • Exact value: 1 lbf = 4.44822 N.
  • Relationship: Defined using Earth’s standard gravity (9.80665 m/s²).
  • Abbreviation: lbf (commonly written as lbs in everyday use).
  • Usage: Engineering, mechanics, aerospace, and daily measurements in the US.

What is a Newton (N)?

newton is the SI unit of force, defined as the force required to accelerate a mass of one kilogram by one meter per second squared.

Key Facts About Newtons

  • Exact value: 1 N = 0.22481 lbf.
  • Relationship: Linked to Newton’s second law of motion (F = m × a).
  • Abbreviation: N.
  • Usage: Physics, mechanics, structural engineering, and scientific research.
