Questions, bug reports and suggestions are welcome. Email us at hello@example.com and we will reply as soon as we can.

If you are reporting a problem, it helps to include:

• what you were trying to do and what happened instead,
• your browser and device (for example “Chrome on Windows 11” or “Safari on iPhone”),
• a link to the calculation (use “Copy link” on the calculator), so we can see the same result.

You can also ask other users for help on our community site.
