About the Center of Gravity 2D Calculator Online Free Tool

The Center of Gravity 2D Calculator Online Free Tool computes the weighted centroid of point masses from x, y, and mass values.

How to Use the Center of Gravity 2D Calculator Online

1. Enter one point per line in the format x,y,mass.
2. Use consistent units for x and y coordinates.
3. Run the calculator to review total mass and X/Y center of gravity.

Choosing Options Correctly

Use positive masses and consistent coordinate references. For distributed shapes, split the geometry into known component centroids and enter each component mass or area as the weight.

Common Use Cases

• Find the center of gravity for a 2D layout.
• Combine component masses in a simple assembly.
• Check balance changes after moving a component.

Quick FAQ

Can I enter areas instead of masses?
Yes, if all areas have the same thickness and density. Otherwise use actual weights or masses for each component.

Does this handle 3D center of gravity?
No. It calculates a 2D weighted centroid from x and y coordinates only.

What if a component has negative weight?
Negative values can represent cutouts in an area centroid, but they should be used carefully and checked against the intended geometry.

Can I use it for lifting or rigging decisions?
Use it as a calculation aid only. Lifting plans need verified weights, 3D CG, sling geometry, dynamic effects, and qualified review.
