Cubic inches to cubic millimeters
Type a value in in³ to get it in mm³ instantly.
1,638,706mm³
That's 2.9× as strong in bending as an IPE 300 steel beam, while a W14×90 column is 1.43× stronger in bending. In S235 steel it reaches yield at about 385.1 kN·m of bending.
Convert the other way: mm³ to in³
What it means
How strong is that beam?
The moment uses a stress of 235 MPa, the yield of S235 steel (A36 is 250 MPa), with no safety factor. Design to your code.
The math
How to convert in³ to mm³
To convert cubic inches to cubic millimeters, multiply by 16,387.1.
Example: 100 in³ × 16,387.1 = 1,638,710 mm³.
In the other direction, 1 mm³ = 6.102×10⁻⁵ in³.
