What is a Newton?

The newton is the SI unit of force, measuring push or pull on an object. Named after Isaac Newton, it equals the force needed to accelerate one kilogram at one meter per second squared (1 kg⋅m/s²).

History of the Newton

Named after Sir Isaac Newton (1643-1727) who formulated the laws of motion. Officially adopted as the SI unit of force in 1948 at the 9th General Conference on Weights and Measures.

Quick Answer

What is a Newton? A newton (N) is the SI unit of force equal to 1 kg⋅m/s². It's the force needed to accelerate 1 kg at 1 m/s². For reference: 1 N ≈ weight of a small apple, 10 N ≈ strong push, 686 N ≈ weight of 70 kg person. Use our force converter to convert newtons to pounds-force, kilonewtons, and other units instantly.

Definition

The newton (N) is the SI unit of force. 1 N = force to accelerate 1 kg mass at 1 m/s².

Formula: F = ma (Force = mass × acceleration)

Conversions:

  • 1 N = 0.225 lbf (pounds-force)
  • 1 N = 0.102 kgf (kilogram-force)
  • 1000 N = 1 kN (kilonewton)

History

Named after Isaac Newton who formulated F = ma in 1687. Adopted as SI unit in 1948.

Common Uses

Engineering: Structural loads, material testing, mechanical design.
