Equivalents

Newton9.80665 N
Dyne980665 dyn
Kilopond (kilogram-force)1 kp · kgf
Pound-force2.204622622 lbf

Converts the value to newtons with these equivalences:

  • 1 dyne = 10⁻⁵ N (CGS unit)
  • 1 kilopond = 1 kgf = 9.80665 N (the weight of 1 kg under standard gravity)
  • 1 pound-force ≈ 4.44822 N (the weight of 1 pound under standard gravity)

Use cases

  • Solving physics problems across unit systems.
  • Reading forces in older (kp, kgf) or US (lbf) spec sheets.
  • Converting an object's weight to newtons.

Technical details

  • Kilopond and pound-force use conventional standard gravity (9.80665 m/s²), not the actual local gravity.
  • Results use 10 significant figures; very large or very small values are shown in scientific notation (e.g. 1e-10).

Frequently asked questions

How many newtons does a kilogram weigh?
