# Section Modulus - Unit Converter

## Convert between Elastic Section Modulus units.

The Elastic Section Modulus of a beam is the ratio of the cross section Area Moment of Inertia to its greatest distance from the neutral axis.

For a simple solid Square the Section Modulus can be expressed as

Sx = Sy = a3 / 6                                         (1)

where

S = Elastic Section Modulus - related to bending around x vs. y axis (m3, cm3, ft3, in3)

a = square side distance (m, in, ft..)

#### Example - Convert Section Modulus in unit in3 to cm3

12 in3 can be converted to cm3 by multiplying with 16.38 - as

(12 in3) (16.38 cm3/in3) = 196.6 cm3
