This free calculator is great for easy calulations:

Just plug in the numbers and instantly know.

Formula:

BORE (mm) X BORE (mm) X STROKE (mm) X 0.0031416 = Engine Displacement in CC's

Example: 92 X 92 X 69 X .0031416 = 1835cc

This may be for a twin cylinder engine. Try using this formula without the second BORE calculation.
