What Flywheel Energy Calculator does
The Flywheel Energy Calculator determines the kinetic energy stored in a rotating flywheel system. Users input the moment of inertia and angular velocity to receive an instant, accurate calculation of the total mechanical energy available. The tool is designed for engineers, physicists, and students studying rotational dynamics, offering a straightforward way to assess energy storage without manual computation. Results are displayed immediately after entering the required parameters. The site provides clear explanations of core concepts, such as moment of inertia and its dependence on mass distribution, along with references to SI standards from NIST and BIPM. Unit selection is supported through dropdowns for both inertia (kg·m², lb·ft², etc.) and angular velocity (RPM, rad/s), making the calculator accessible to users regardless of their preferred measurement system.

Flywheel Energy Calculator FAQ
- What is moment of inertia and how does it affect flywheel energy?
- Moment of inertia measures how difficult it is to rotate an object around an axis, depending on mass distribution relative to the rotation axis. It directly determines the amount of kinetic energy a flywheel can store for a given angular velocity.
- Which units are supported for moment of inertia and angular velocity?
- The calculator supports multiple units for moment of inertia, including kilogram square metre (kg·m²) and pound square foot (lb·ft²). Angular velocity can be entered in revolutions per minute (RPM) or radians per second (rad/s).
- Are the results based on standard physical constants?
- Yes, the tool uses internationally agreed factors maintained by NIST and authoritative definitions from the BIPM SI Brochure (9th edition) for moment of inertia measurements.
- Is any software or registration required to use the calculator?
- No signup is required, and the tool runs directly in the browser. It is a free online calculator accessible without downloading any software.
