Force Converter – Newtons, kgf & lbf Table

This force unit converter routes every input through exact definitions — 1 kgf = 9.80665 N and 1 lbf = 4.4482216 N exactly. Enter a value, pick the source and target units, and the result appears instantly with the factor applied shown beside it. Newtons express force in SI, kilogram-force survives in everyday speech and old machinery plates, and pound-force anchors US engineering — three vocabularies describing the same push. The standard links them exactly: 1 kgf = 9.80665 N and 1 lbf = 4.4482216152605 N, both by international definition tied to standard gravity. A mini table of the head factor makes spot-checks immediate: 1 kgf = 9.8066 N; 5 kgf = 49.0332 N; 10 kgf = 98.0665 N; 50 kgf = 490.3325 N; 100 kgf = 980.665 N. Feel the scale: an apple weighs about 1 N, a liter of water pushes down with 9.8 N, and an adult standing still loads the floor with roughly 700 N.

   Read the exact result, then swap or copy as needed

• 1

  Spec sheets written "daN" mean dekanewrons = 10 N each

• 2

  Standard gravity is a convention, not your location's value

• 3

  1 lbf ≈ 4.448 N; 100 lbf ≈ 445 N for quick checks

• 4

  1 kgf = 9.80665 N — carry all five decimals in engineering work

• Using local gravity (9.78–9.83 m/s²) where the standard 9.80665 is specified

• Mixing lbf·ft torque with N·m without converting the force and length both

• Reading "kg" on a European crane plate as mass when it means kgf loading
