How to Calculate Deck Height into CC's

the inch system

Formula - Bore (in.) X Bore (in.m) X Stroke (in.) X 12.87 = Deck in CC
Example - 90.5mm = 3.563" X 3.563" X .060" X 12.87 = 9.80cc
1mm = .03937

or the mm system

Formula - Bore (mm) X Bore (mm) X Deck Height (in.) X .01996 = Deck in CC
Example - 90.5 X 90.5 X .060" X .01996 = 9.80cc

Deck Piston - Deck Height in CC's

How to Calculate Engine CC's

Formula - Bore (mm) X Bore (mm) X Stroke (mm) X 3.1416" = Engine cc
Example - 90.5 X 90.5 X 69mm X 3.1416 = 1775cc (to get the Volume of 1 cylinder in CC divide by 4)
Example - 1775 ÷ 4 = 443.75

Bore Stroke - Engine Displacement in CC's
