Find the combined centre of mass from item weights and centre positions, with an X/Y illustration.

Result
Enter your data or use the example, then run the tool.
Worked example
10 kg at X=0 and 30 kg at X=2 gives centre X=1.5; shifting both positions by +5 shifts the centre by +5.
Method
Use one origin and unit for all positions. For each axis, multiply every item’s mass by its coordinate, add those values and divide by total mass. Include the packaging as another item if it contributes weight.
Limits
Each item is treated as mass concentrated at its entered centre, and total mass must be positive. This does not assess stacking stability, lifting, forklifts, axle loads or transport compliance. The diagram shows the X/Y plane only.
