Reporting a calculation error
To help us check a result quickly, please include:
- the calculator page address (URL);
- the values you entered, including the units you selected;
- the result you received and the result you expected;
- if possible, how you calculated the expected value or the source you compared against.
Confirmed errors are corrected, re-tested and reflected in the calculator's "last reviewed" date.
Suggesting a calculator
Tell us what you're trying to work out, which inputs you have, and what the result should show. Suggestions help us decide what to build next.
What we can't help with
We can't provide personal financial, medical, legal or engineering advice, review your specific project, or guarantee that a result suits your situation. Please consult a qualified professional for those needs.
Please don't send sensitive personal information (such as account numbers or medical records) by email. See our Privacy Policy for how we handle messages.
