How many cubic inches in 1 cubic unit?

Answer 1

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
