The general equation for Moment of Inertia for bending around an axis can be expressed as
Iaxis = ∫ y2 dA (1)
Iaxis = Area Moment of Inertia related to an axis (m4, mm4, in4, ft4)
y = the perpendicular distance from axis to the element dA (m, mm, in, ft)
dA = an elemental area (m2, mm2, in2, ft2)

Example - Convert between Area of Inertia Units
To convert from 160.6 cm4 to in4 multiply with 2.4 10-2 as
(160.6 cm4) 2.4 10-2 = 3.9 in4
