What Is This Tool?
This converter translates force values from kilogram-force (kgf), a non-SI unit based on Earth's gravity, into newtons (N), the SI unit for force. It helps standardize measurements for scientific and engineering applications.
How to Use This Tool?
-
Enter the force value in kilogram-force [kgf].
-
Select kilogram-force as the source unit and newton [N] as the target unit.
-
Click convert to obtain the equivalent force in newtons.
Key Features
-
Converts force units from kilogram-force to newton accurately based on a defined conversion rate.
-
Browser-based tool for quick and convenient calculations.
-
Supports applications in engineering, physics, and legacy data interpretation.
Examples
-
2 kgf equals 19.6133 N by multiplying 2 × 9.80665.
-
5 kgf converts to 49.03325 N by multiplying 5 × 9.80665.
Common Use Cases
-
Interpreting older engineering specifications and spring rates given in kilogram-force.
-
Converting hand tool ratings specifying pull force in kgf to SI units.
-
Standardizing force data from legacy equipment for modern engineering analysis.
Tips & Best Practices
-
Always verify units before conversion to avoid mixing SI and non-SI measurements.
-
Use this tool to ensure force values are compatible with standard engineering calculations.
-
Keep in mind the assumption of standard gravity when interpreting values.
Limitations
-
Kilogram-force is not an official SI unit and may cause confusion if used without conversion.
-
The conversion is based on standard gravity, which can slightly vary depending on location.
Frequently Asked Questions

What is 1 kilogram-force equal to in newtons?
-
One kilogram-force is defined as exactly 9.80665 newtons.
-
Why convert kilogram-force to newtons?
-
Converting to newtons standardizes force measurements to the SI unit, improving compatibility in engineering and scientific contexts.
-
Can kilogram-force be used interchangeably with newtons?
-
No, kilogram-force is not an SI unit and can cause confusion without conversion to newtons.
Key Terminology
-
Kilogram-force [kgf]
-
A gravitational unit of force defined by the force exerted by gravity on a one kilogram mass, equal to 9.80665 newtons.
-
Newton [N]
-
The SI derived unit of force, equal to the force needed to accelerate one kilogram of mass at one meter per second squared.
-
Standard Gravity
-
The constant acceleration due to gravity defined as 9.80665 m/s², used as the basis for kilogram-force.
