How to Convert Cubic Inches to Cubic Millimeters

Conversion factor:

1 in3=16387.1 mm31\,\mathrm{in}^{3} = 16387.1\,\mathrm{mm}^{3}

Inverse factor:

1 mm3=0.00006102 in31\,\mathrm{mm}^{3} = 0.00006102\,\mathrm{in}^{3}

Example

Convert 15 in³ to mm³:

mm3=in3×16387.1\mathrm{mm}^{3} = \mathrm{in}^{3} \times 16387.1
mm3=15×16387.1\mathrm{mm}^{3} = 15 \times 16387.1
mm3=245806.5\mathrm{mm}^{3} = 245806.5
=245806.5 mm3= 245806.5 \, \mathrm{mm}^{3}
