How to convert from square inches (in2) to cubic centimeters (cm3)?
The area in square inches (in2) must be multiplied by the thickness in inches and multiply by 16.387. The result is a volume of cubic centimeters (cm3).
1 cm3 ≈ 1 in2 * 1 in * 16.387
1 cm3 = 1 in2 * 1 in * 2.54 * 2.54 * 2.54 = 1 in2 * 1 in * 16.387064
1 in = 2.54 cm
