Frequently Asked Questions

What is gravitational potential energy?

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It depends on the object's mass, height above a reference point, and the gravitational acceleration.

What is the reference point for height?

The reference point is typically the ground level or the lowest point in the system. Height is measured from this reference point to the object's position.

What units are supported?

The calculator supports multiple units for mass (kg, g, lb, oz), height (m, cm, km, ft, in, mi), and energy (J, kJ, cal, kcal, Wh, kWh). All conversions are handled automatically.

Can I use this for other planets?

Yes, you can change the gravity value to match other celestial bodies. For example, use 1.62 m/s² for the Moon or 3.71 m/s² for Mars.

Is my data secure?

Yes, all calculations happen locally in your browser. Your data never leaves your device.

Can I use this offline?

Yes, once loaded, the calculator works completely offline in your browser.
