0.00 N
Force in Newtons
Conversion factor: 1 kilogram-force = 9.80665 Newtons
The kilogram-force is the force exerted by one kilogram of mass in Earth's gravitational field.
Kilogram-force to Newton Conversion Calculator
This calculator converts force values from kilogram-force (kgf) to Newtons (N), the standard SI unit of force. The kilogram-force is a gravitational metric unit of force, representing the force exerted by one kilogram of mass in Earth's standard gravitational field.
F(N) = F(kgf) × 9.80665
The conversion factor 9.80665 m/s² represents the standard gravitational acceleration defined for the kilogram-force unit. This value ensures precise conversion between the gravitational unit system and the International System of Units (SI).
Conversion Example:
Convert 5 kgf to Newtons:
F(N) = 5 kgf × 9.80665 = 49.03325 N
Technical Note: The kilogram-force was historically used in engineering applications before the adoption of SI units. One kilogram-force equals the gravitational force acting on a mass of one kilogram under standard Earth gravity (g₀ = 9.80665 m/s²).
| Kilogram-force (kgf) | Newton (N) |
|---|---|
| 1 kgf | 9.80665 N |
| 10 kgf | 98.0665 N |
| 100 kgf | 980.665 N |
| 1000 kgf | 9806.65 N |
The calculator allows you to set the decimal precision for results, making it suitable for both engineering calculations requiring high precision and general purpose conversions. This tool is essential for engineers, students, and professionals working with force measurements in different unit systems.
