Oh honey, let me break it down for you. Horsepower and engine displacement are like apples and Oranges - they just don't mix. 18 horsepower is a unit of power, while cc (cubic centimeters) measures engine displacement. So, there's no direct conversion between the two. It's like asking how many inches are in a pound - they just don't play in the same sandbox, darling.
