How many horse power is 87 cc?

To convert cubic centimeters (cc) to horsepower, a general rule of thumb is that 1 horsepower is approximately equivalent to 15 cc for small engines. Therefore, an 87 cc engine would be roughly equivalent to about 5.8 horsepower (87 cc ÷ 15 cc/hp). However, this is a rough estimate, as actual horsepower can vary based on engine design and efficiency.
