Calculate Engine Size in Cubic Inches and CC's

Engine Calculator

  • Enter Bore Size Bore/Stroke Ratio (B/S)  :1
  • Enter Stroke size    Rod/Stroke Ratio (R/S)   :1
  • Number of Cylinders  CI Engine Size ci
  • Enter Rod Length    CC Engine Size cc

                 
Notes
Calculate CI from Bore, Stroke, and Number of cylinders
Calculate Bore from Engine Size, Stroke, and Number of cylinders
Calculate Stroke from Engine Size, Bore, and Number of cylinders
Calculate Rod Stroke Ratio from Stroke and Rod Length
