Frequently Asked Questions
-
What does kilogram square meter measure?
-
Kilogram square meter is the SI derived unit measuring moment of inertia, representing an object's resistance to angular acceleration based on mass and distance squared from the rotation axis.
-
Why convert to kilogram-force meter square second?
-
Converting to kilogram-force meter square second helps express moment of inertia values in units used by legacy engineering documents and systems where gravitational force units are standard.
-
Is kilogram-force meter square second an SI unit?
-
No, kilogram-force meter square second is a non-SI derived unit and should be used carefully alongside SI units to avoid unit mismatches.
Key Terminology
-
Kilogram square meter (kg·m²)
-
An SI derived unit measuring moment of inertia, calculated as mass times the square of the distance from the axis of rotation.
-
Kilogram-force meter square second (kgf·m·s²)
-
A non-SI unit of moment of inertia equivalent to one kilogram-force times one meter times one second squared, used in some engineering fields and legacy contexts.
-
Moment of inertia
