About the Newton
Newton (N) is a unit of force measurement. 1 newton is equal to 0.1019716 kilogram-force.
The Kilogram-force in Engineering
Kilogram-force (kgf) is a unit of force measurement. 1 kilogram-force is equal to 9.8066500 newton.
Force Units in Engineering
Force measurement splits between SI (newtons, kilonewtons) and legacy systems (pound-force, kilogram-force, dynes). Structural engineers, automotive crash testers, aerospace designers, and material scientists all encounter mixed unit systems in international specifications, test reports, and historical reference documents. Converting accurately between these is critical for safety calculations.

How to Convert N to KGF (Newton to Kilogram-force)?
We can convert newton to kilogram-force by using an example.
Example:
Convert 20 Newton to Kilogram-force?
We know 1 Newton = 0.1019716 kilogram-force; 1 Kilogram-force = 9.8066500 newton.
20 newton = ___kgf
20 × 0.1019716 = 2.03943 kgf (we know 1 newton = 0.1019716 kilogram-force)
Answer:
20 newton = 2.03943 kilogram-force
How to Convert Newtons to Kilogram-Force (Weight Equivalent)
Converting Newtons to kilogram-force (kgf) bridges the gap between scientific force measurement and everyday weight understanding. One Newton equals approximately 0.10197 kgf, derived from the relationship F = mg where g = 9.80665 m/s². This conversion is essential in gym equipment calibration, elevator load ratings, and packaging weight limits.
- Start with your force value in Newtons (N).
- Divide the Newton value by 9.80665 (standard gravitational acceleration).
- Alternatively, multiply by 0.10197 to get the same result.
- The result is the equivalent force in kilogram-force (kgf).
- Verify: your kgf value should be roughly 1/10 of the Newton value.
Newton to Kilogram-Force Reference Table
Frequently encountered force values in physics labs, gyms, and engineering contexts:

Solved Examples: Newtons to Kilogram-Force
Question 1: A spring scale reads 245 N. What is the equivalent in kgf?
Solution:
Force in kgf = Force in N ÷ 9.80665
= 245 ÷ 9.80665
= 24.98 kgf
Answer: 245 N ≈ 24.98 kgf — roughly a 25 kg weight on the scale.
Question 2: An elevator cable sustains a tension of 7,500 N. Express in kgf.
Solution:
Force in kgf = 7500 ÷ 9.80665
= 764.78 kgf
Answer: 7,500 N = 764.78 kgf — about the weight of 7-8 adults.
Question 3: A laboratory force sensor reads 0.35 N during a friction experiment. Convert to kgf.
Solution:
Force in kgf = 0.35 ÷ 9.80665
= 0.03569 kgf
= 35.69 gf (gram-force)
Answer: 0.35 N ≈ 0.0357 kgf or about 35.7 gram-force.

Weight vs. Force: Why the Distinction Matters
Mass (kg) and weight (kgf or N) are different physical quantities. Mass is intrinsic — a 70 kg person has 70 kg of mass on Earth, the Moon, or in space. Weight is the gravitational force on that mass: 686.5 N on Earth but only 113.4 N on the Moon. The kilogram-force unit conflates mass and weight, which is why scientists prefer Newtons. However, kgf remains practical in everyday engineering where gravity is constant.
Where Kilogram-Force Is Still Used Today
Despite being deprecated in strict SI usage, kgf appears on gym equipment (a "50 kg" weight stack), tire pressure gauges (kgf/cm²), torque wrenches in older specifications, and Asian industrial standards. Many elevator load plates still list capacity in kgf. Understanding the N-to-kgf conversion helps engineers read legacy specifications and communicate with non-technical stakeholders who think in "kilograms of force."
Key Takeaways
- 1 N = 0.10197 kgf (divide Newtons by 9.80665).
- Kilogram-force represents the weight of 1 kg under standard gravity.
- Quick shortcut: divide N by 10 for an approximate kgf value.
- kgf is still common in gyms, elevators, and legacy engineering specs.
- On the Moon, the same mass produces only ~1/6 the kgf value it does on Earth.
