Kilonewton to Kilogram-force Conversion
1 kN = 101.9716 kgf
1 kgf = 0.00980665 kN
kgf = kN × (1000 / 9.80665)
kN = kgf × 0.00980665
Convert 5 kN to kgf:
kgf = kN × 101.9716
kgf = 5 × 101.9716
kgf = 509.858 (with 3 decimal places)
Convert 200 kgf to kN:
kN = kgf × 0.00980665
kN = 200 × 0.00980665
kN = 1.96133 (with 5 decimal places)

Common questions about Kilonewton, Kilogram-force, and force unit conversions.
There are exactly 101.9716 Kilogram-force (kgf) in 1 Kilonewton (kN). This conversion is derived from the standard gravitational acceleration constant (g = 9.80665 m/s²) and Newton's second law of motion (F = m × g).
1 kN = 1000 N (since 1 kilonewton = 1000 newtons)
1 kgf = 9.80665 N (force of 1 kg mass under standard gravity)
1 kN = 1000 / 9.80665 ≈ 101.9716 kgf
This conversion factor is fixed and widely used in engineering and physics applications for accurate force unit translations.
The key differences between Kilonewton (kN) and Kilogram-force (kgf) lie in their classification, definition, and usage:
While both measure force, kN is the preferred unit for global and scientific applications, while kgf is still used in some traditional engineering practices.
The conversion factor 101.9716 is derived from the mathematical relationship between newtons (the base SI unit of force) and kilogram-force, combined with the kilonewton's definition:
Conversion Factor = 1000 (N/kN) / 9.80665 (N/kgf) ≈ 101.9716 (kgf/kN)
This factor is constant because it is based on the internationally agreed-upon standard gravitational acceleration (9.80665 m/s²).
Kilonewton (kN) and Kilogram-force (kgf) are both widely used in engineering and industrial fields, with slight differences in their primary applications:
Many modern industries now adopt kN (SI unit) for global compatibility, but kgf remains prevalent in legacy systems and regional practices.
You can use approximate conversion factors for quick, non-critical calculations, but precision matters for engineering and scientific applications:
This converter uses the exact conversion factor to ensure accuracy for engineering and professional applications.
