What is Pound-Force (lbf)?
A 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)?
A 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.
