How to convert from square inches (in2) to cubic meters (m3)?
The area in square inches (in2) must be multiplied by the thickness in inches and divide by 61024. The result is a volume of cubic meters (m3).
__ m3 ≈ __ in2 x __ in / 61024
__ m3 = __ in2 x __ in / (1/0.0254×1/0.0254×1/0.0254) ≈ __ in2 x __ in / 61023.744
1 in = 2.54 cm = 0.0254 m ⇒ 1 m = 1/0.0254 in
