Kilogram-force (kgf)
The kilogram-force (kgf, also kilopond kp) is the weight of 1 kg under standard gravity, exactly 9.80665 N.
Symbol: kgf
Quantity: force
SI relation: 1 kgf = 9.80665 N (exact)
Derivation: 1 kgf = 1 kg × 9.80665 m/s² = 9.80665 N (exact)
Exact: yes, by definition
Typical uses
- Older metric engineering data and gauges (kgf/cm²)
- Hand grip and pull strength
- Load cells and scales labelled in kg
