Kilogram-force per square millimeter is a non-SI unit and may cause confusion without clear notation
-
Conversion involves a very small factor which can introduce rounding errors
-
This unit is less common in current engineering practice outside legacy contexts
Frequently Asked Questions
-
What is the pascal unit?
-
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
-
Why convert pascal to kilogram-force per square millimeter?
-
To interpret pressure or stress values in terms commonly used in materials testing and certain engineering fields that use gravitational units.
-
Is kilogram-force per square millimeter an SI unit?
-
No, it is a non-SI gravitational unit commonly found in older technical literature and specific engineering applications.
Key Terminology
