How does the Tidal Force Calculator work?

Input primary mass, satellite mass, separation distance Then: Calculate tidal force gradient Then: Compare to self-gravity.

Can you give an example of how to use the Tidal Force Calculator?

Example: Input Earth-Moon system gives a result of Tidal force sufficient to cause 1m ocean tides (Moon receding ~3.8 cm/year).

Is the Tidal Force Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Tidal Force Calculator?

Our Tidal Force Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
