| + | * Cubic Centimeters to Cubic Inches: cc ÷ (2.54 cubed) (example: 1200cc) = 1200 ÷ (2.54 cubed) = 73.23ci | ||
| + | * Cubic Inches to Cubic Centimeters: ci x (2.54 cubed) (example: 100ci) = 100 x (2.54 cubed) = 1638.7cc | ||
| + | * Horsepower: (torque x rpm) ÷ 5252 (example: 80 ft-lbs at 4000 rpm) = (80 x 4000) ÷ 5252 = 60.93hp | ||
| + | * Torque: (horsepower x 5252) / rpm (example: 100hp at 4000 rpm) = (100 x 5252) ÷ 4000 = 80 x 4000) / 5252 = 131 ft-lbs. | ||
