How Force Conversion Works
Force is a fundamental physical quantity that describes the interaction between objects. Different measurement systems (metric vs imperial) and scientific applications require conversion between various force units for engineering calculations and international collaboration.
Conversion Formulas Between Common Units
Newtons ↔ Pounds-force
1 N = 0.224809 lbf
1 lbf = 4.44822 N
Newtons ↔ Kilograms-force
1 N = 0.101972 kgf
1 kgf = 9.80665 N
Newtons ↔ Dynes
1 N = 100,000 dyn
1 dyn = 0.00001 N

Physics Formulas
Newton's Second Law
F = m × a
where F is force, m is mass, and a is acceleration
Weight Force
W = m × g
where W is weight, m is mass, and g is gravitational acceleration (9.81 m/s²)
Spring Force (Hooke's Law)
F = k × x
where k is spring constant and x is displacement
Friction Force
F = μ × N
where μ is coefficient of friction and N is normal force
