What Is This Tool?
This converter enables you to translate pressure or mechanical stress measurements from newton per square millimeter (N/mm²), an SI unit equal to one megapascal, into kilogram-force per square millimeter (kgf/mm²), a non-SI gravitational unit commonly used in engineering charts and older technical literature.
How to Use This Tool?
-
Enter the pressure value in newton/square millimeter (N/mm²).
-
Select the target unit as kilogram-force per square millimeter (kgf/mm²).
-
Click convert to obtain the equivalent pressure in kgf/mm².
Key Features
-
Easy conversion between newton/square millimeter and kilogram-force/sq. millimeter.
-
Supports units frequently used in materials engineering, structural, and mechanical design.
-
Browser-based and user-friendly interface for quick pressure unit translation.
Examples
-
5 N/mm² equals 0.5098581065 kgf/mm² after conversion.
-
10 N/mm² converts to 1.019716213 kgf/mm².
Common Use Cases
-
Translating tensile or yield strength values of metals and alloys for engineering analysis.
-
Interpreting compressive strength data of concrete, rock, or other structural materials.
-
Converting hydraulic system pressures in mechanical design contexts.
-
Reviewing older datasheets or charts that use kilogram-force units.
Tips & Best Practices
-
Always verify the unit used in original data sources before conversion.
-
Use the converter to compare SI-based and gravitational metric unit measurements accurately.
-
Be cautious when interpreting kilogram-force units in strict SI environment to avoid confusion.
Limitations
-
Kilogram-force per square millimeter is a non-SI gravitational unit that may not be suitable in strict SI contexts.
-
Conversion accuracy depends on the gravitational constant underlying the kilogram-force definition.
-
Older technical documents may use this unit inconsistently, requiring careful interpretation.
Frequently Asked Questions
-
What is the relationship between newton/square millimeter and kilogram-force/sq. millimeter?
-
1 newton/square millimeter equals approximately 0.1019716213 kilogram-force per square millimeter.
-
Why is kilogram-force per square millimeter considered a non-SI unit?
-
Because it is based on gravitational force and not part of the International System of Units (SI), which relies on base units defined independently of gravity.
-
In which fields is converting between these units most commonly used?
-
Conversions are frequent in materials engineering, structural analysis, mechanical design, metallurgy, and hydraulic system engineering.
Key Terminology
-
Newton/square millimeter (N/mm²)
-
An SI pressure unit representing one newton of force applied over an area of one square millimeter, equivalent to one megapascal.
-
Kilogram-force per square millimeter (kgf/mm²)
-
A gravitational pressure unit representing one kilogram-force applied to one square millimeter area; a non-SI unit used in older engineering contexts.
-
Pressure
-
The force exerted perpendicular to the surface of an object per unit area over which that force is distributed.
