How many horsepower is 64cc?

The power output of an engine is typically measured in horsepower (hp) or kilowatts (kW) rather than directly in cubic centimeters (cc). However, a rough estimate places small engines around 1 horsepower for every 15-20 cc. Therefore, a 64cc engine might produce approximately 3 to 4 horsepower, depending on factors like engine efficiency and design.
