Frequently asked questions
A calculator gave a result I did not expect. What should I do?
First check the units and the formula explained on that tool's page. If you still think the result is wrong, email us the tool name and your inputs, and we will check it and fix any error.
Can I request a calculator for my business or school?
Yes. Describe what you need to calculate and an example of the expected result. We cannot build every request, but useful ideas are added for everyone.
Do you offer financial, medical or legal advice?
No. Our tools give general estimates only. Please consult a qualified professional for personal advice. See our disclaimer.
