Common values

  • 1 kgf = 9.80665 N (the weight of 1 kg)
  • 1 lbf = 4.4482 N
  • 1 N = 0.2248 lbf
  • 1 dyne = 10 µN (very small CGS unit)

FAQ

Why does 1 kg of "weight" map to 9.81 N?

Mass and weight are different. 1 kg is mass; under Earth's gravity (g = 9.80665 m/s²) that mass exerts a downward force of 9.80665 N — also called 1 kgf.
