Force Conversion Reference
SI Units (Newtons)
- Newton (N): SI unit of force. 1 N = 1 kg·m/s². The force required to accelerate 1 kilogram at 1 meter per second squared.
- Kilonewton (kN): 1 kN = 1000 N. Commonly used in structural engineering and construction for loads and forces.
- Meganewton (MN): 1 MN = 1,000,000 N. Used for very large forces in heavy engineering and aerospace applications.
- Millinewton (mN): 1 mN = 0.001 N. Used for small forces in precision instruments and micro-mechanics.
- Micronewton (µN): 1 µN = 0.000001 N. Used for very small forces in nanotechnology and precision physics.
- Dyne (dyn): 1 dyn = 0.00001 N = 10⁻⁵ N. CGS unit of force, rarely used in modern applications.
Metric Gravitational Units
- Kilogram-force (kgf): 1 kgf = 9.80665 N. Force exerted by 1 kilogram of mass under standard gravity. Also called kilopond (kp).
