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

*W _{x} = W_{y} = a^{2} / 6 (1)*

*where *

*W = Elastic Section Modulus - related to bending around x vs. y axis (m ^{3}, cm^{3}, ft^{3}, in^{3})*

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

#### Example - Convert Section Modulus in unit* in*^{3} to *cm*^{3}

^{3}

^{3}

*12 in ^{3} *can be converted to

*cm*by multiplying with

^{3}*16.38*- as

*(12 in ^{3}) (16.38 cm^{3}/in^{3}) = 196.6 cm^{3}*
