What is Center of Mass Calculator?
In the fields of physics and engineering, the center of mass helps describe how mass is distributed along a line. The Center of Mass Calculator turns a list of mass-and-position pairs into a single X-coordinate so you can quickly analyze balance problems, beam layouts, or simple statics exercises. It is designed for 1D calculations and works directly in the browser.

Frequently Asked Questions
Can positions be negative?
Yes. Negative positions are allowed if they reflect the coordinate system you are using.
Does this tool work in more than one dimension?
No. It is intended for one-dimensional center of mass calculations.
What happens if all masses are the same?
The result becomes the simple average of the positions, which is the geometric center.
