Question: how to calculate engine displacement in cc?
Answer: Engines are usually given a size of displacement in cm3 or commonly referred to as CC's. To convert your answer to CC's, divide your answer by 1000. In this example, you would have 452,160mm3 ÷ 1000 giving you an answer of 452.16 cm3 or 452.16 cc. This engine has a displacement of 452.16 cm3 or 452.16 cc.
