Engine Type Ratio:
32.5 CC / HP (4-stroke OHV)
HP ≈ 212 / 32.5 = 6.5 HP
How to Convert CC to HP
CC (Cubic Centimeters) measures cylinder displacement (engine volume), whereas Horsepower (HP) measures the rate of mechanical work output. For small 4-stroke small utility engines (Honda GX, Briggs & Stratton, Predator), standard industry rule of thumb is 30 to 35 CC per 1 HP (averaging 32.5 CC/HP).
