It all depends upon what the unit is.

For example:

  • If the unit is centimetres, then:
1 in = 2.54 cm

⇒ 1 cu in = 1 in x 1 in x 1 in

= 2.54 cm x 2.54 cm x 2.54 cm

= 16.387064 cu cm

≈ 16.387 cu cm

  • If the unit is feet, then:
1 in = 1/12 ft

⇒ 1 cu in = 1 in x 1 in x 1 in

= 1/12 ft x 1/12 ft x 1/12 ft

= 1/1728 cu ft

≈ 0.000579 cu ft
