Units of horsepower (HP) measure power output, while cubic centimetre (CC) units measure volume. Since each is used to measure different things, there is no easy calculator for direct conversion, but there is a formula that you can use to convert CC to HP. As a general rule related to vehicle engines, 15 CC = 1 HP. So a 1500 CC engine is roughly equivalent to a 100 HP engine.
Turn on the calculator.
Enter the CC number in the calculator.
Press the division sign.
Enter the number 15.
