100cm⁴
That's 2,037× as stiff as a 10 mm steel rod, while a timber stud is 2.2× stiffer. A solid square beam about 58.86 mm a side would be just as stiff.
What it means
How stiff is that section?
This is the area moment, about a stated axis. It is not the mass moment of inertia, which has units of kg·m² and belongs to spinning things.
The math
How to convert mm⁴ to cm⁴
To convert millimeters to the fourth to centimeters to the fourth, multiply by 0.0001.
Example: 1,000,000 mm⁴ × 0.0001 = 100 cm⁴.
In the other direction, 1 cm⁴ = 10,000 mm⁴.
