Convert section modulus units including cubic inches, cubic feet, cubic millimeters, cubic centimeters, and cubic meters for beams, joists, steel shapes, wood members, bending stress, and structural estimates.
Cubic inches to cubic millimeters:
1 in³ = 16,387.064 mm³
Cubic feet to cubic inches:
1 ft³ = 1,728 in³
Cubic centimeters to cubic inches:
1 cm³ = 0.0610237 in³
Cubic meters to cubic inches:
1 m³ = 61,023.744 in³
Section modulus conversions are useful for beams, joists, rafters, steel shapes, wood members, aluminum shapes, structural sections, bending stress checks, section tables, and engineering plan review.
Use this converter when switching between imperial and metric section modulus units for structural calculations and material comparisons.
Your result shows the entered section modulus converted from the starting unit into the selected ending unit. The converter also shows common equivalent values in cubic inches, cubic millimeters, cubic centimeters, and cubic feet.
This converter changes section modulus units only. It does not determine whether a beam is safe. Structural design depends on bending moment, material strength, span, loading, bracing, deflection, connections, and code requirements.
Section modulus is a geometric property used to compare how a shape resists bending. It is commonly used in bending stress calculations.
Multiply cubic inches by 16,387.064. For example, 10 in³ equals 163,870.64 mm³.
Section modulus uses length cubed units, such as in³, ft³, mm³, cm³, or m³.
No. Moment of inertia is measured in length to the fourth power, while section modulus is moment of inertia divided by distance to the extreme fiber.
No. This converter only changes section modulus units and gives a rough bending stress reference when a moment is entered.
