CC, or cubic centimeters, is a measure of volume or size. Engine power is a measure of power output at certain rotational frequencies. Rotation frequencies are measured in revolutions per minute or rpm. Engine power cannot be directly converted to cc because power is measured at rpm levels that are not accounted for by cubic centimeters. While there is no specific formula for converting engine horsepower to cc, on average 1 horsepower equals 16 cc.
Step 1: horsepower to dc
Determine the maximum power of your engine. The peak power of an engine is typically measured at a certain rpm level.
Step 2: cubic centimeters to horsepower
Drop the rpm figure from the horsepower figure. For example, if your engine reaches 150 horsepower at 6,000 rpm, turn down 6,000 and use 150 for your calculation. Use a calculator to multiply the horsepower of your engine by 16. For example, if your engine has 150 horsepower, multiply 150 x 16 = 2,400 cc. This figure represents the horsepower of your engine in cubic centimeters.
Tip: convert cc to horsepower
- The number you get from this conversion is a measure of the volume or size of your engine at full power.
