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).
1 m3 ≈ 1 in2 * 1 in / 61024
1 m3 = 1 in2 * 1 in / (1/0.0254*1/0.0254*1/0.0254) ≈ 1 in2 * 1 in / 61023.744
1 in = 2.54 cm = 0.0254 m ⇒ 1 m = 1/0.0254 in
