Convert force units between metric & imperial systems
Result: -
Force is a fundamental part of the physical world. It moves vehicles, holds structures in place, powers machines, and keeps objects in motion. From building skyscrapers to launching satellites, force measurement accuracy is necessary to prevent failures and ensure safety.
But different disciplines use different units:
Newton (N) – International standard
Kilogram-force (kgf) – Common in mechanical industries
Pound-force (lbf) – Used in the U.S. automotive & aerospace fields
Dyne – Used in micro-scale scientific research
The Free Force Converter by AlllinTools helps engineers, students, and professionals instantly convert force values between all major units — eliminating calculation errors and speeding up design decision-making.
Measure force correctly → Build a safer world.
Force is defined as any interaction that changes the motion of an object.
Newton’s Second Law explains:
Force = Mass × Acceleration
(F = m × a)
Example:
Acceleration: 2 m/s²
Mass: 10 kg
→ Force applied: 20 N
Every movement in life — from pushing a door to launching rockets — uses force.

| Unit | Symbol | Common Usage |
|---|---|---|
| Newton | N | Standard SI engineering use |
| Kilogram-force | kgf | Industrial settings, manual tools |
| Pound-force | lbf | US mechanical & aerospace |
| Dyne | dyn | Scientific micro-scale measurements |
Units vary depending on region, industry, and precision needs — hence conversion is required.
📌 Newton ↔ Kilogram-force
1 kgf = 9.80665 N
📌 Newton ↔ Pound-force
1 lbf = 4.44822 N
1 N ≈ 0.224809 lbf
📌 Newton ↔ Dyne
1 N = 100,000 dynes (1 × 10⁵)
Example conversion:
Applied force: 100 N
→ 22.48 lbf
→ 10.197 kgf
→ 10,000,000 dyn
