Convert section modulus units including cubic inches, cubic feet, cubic millimeters, cubic centimeters, cubic meters, cubic yards, and more.
Cubic inches to cubic millimeters:
1 in³ = 16,387.064 mm³
Cubic centimeters to cubic millimeters:
1 cm³ = 1,000 mm³
Cubic feet to cubic inches:
1 ft³ = 1,728 in³
Cubic meters to cubic millimeters:
1 m³ = 1,000,000,000 mm³
Section modulus conversions are useful for beam design, bending stress checks, steel beam tables, wood member sizing, mechanical shafts, structural shapes, frame design, and section property comparisons.
Use this converter when comparing metric and U.S. customary section modulus values.
Your result shows the entered section modulus converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and structural design, make sure the section modulus unit matches your bending moment unit, stress unit, section table, design code, or beam calculation.
Section modulus is a geometric property used to estimate bending stress in a member.
Section modulus uses cubic length units, such as in³, mm³, cm³, ft³, or m³.
One cubic inch equals 16,387.064 cubic millimeters.
No. Section modulus is moment of inertia divided by the distance to the extreme fiber.
This converter is designed for section modulus magnitude conversions, so it uses non-negative values.
