This n mm² kg/cm² calculator helps you convert between these two pressure units commonly used in engineering, physics, and materials science. Understanding the relationship between these units is essential for accurate measurements and calculations in various scientific and industrial applications.
What is n mm² kg/cm²?
n mm² and kg/cm² are both units of pressure, but they are used in different contexts. The newton per square millimeter (n mm²) is part of the International System of Units (SI), while kilogram-force per square centimeter (kg/cm²) is a traditional unit still used in some engineering fields.
Key difference: 1 kg/cm² ≈ 98.0665 n/mm². This conversion factor accounts for the difference between the gravitational force (kgf) and the SI unit of force (newton).
Both units measure force per unit area, but their definitions and applications vary. The n mm² is more commonly used in modern scientific contexts, while kg/cm² remains relevant in some traditional engineering practices.
Conversion formula
The conversion between n mm² and kg/cm² is straightforward once you understand the relationship between the units:
1 kg/cm² = 98.0665 n/mm²
1 n/mm² = 0.0101972 kg/cm²
These formulas are derived from the fact that 1 kg-force (kgf) is approximately equal to 9.80665 newtons (N), and 1 cm² is equal to 100 mm². The conversion factor is simply the ratio of these two values.
| Unit | Symbol | Definition |
|---|---|---|
| Newton per square millimeter | n mm² | SI unit of pressure (1 N/m²) |
| Kilogram-force per square centimeter | kg/cm² | Traditional unit of pressure (1 kgf/cm²) |
