Common Questions
I found a wrong result. What should I send?
Please include the tool URL, your exact inputs, your timezone (if relevant), and what you expected. Screenshots are helpful too.
Do you store my inputs?
Most tools run entirely in your browser. We do not require accounts. Analytics (if enabled via consent) is used to understand usage trends, not to store calculator inputs as user profiles.
Can I request a new tool?
Yes—send your idea to [email protected]. If possible, describe the exact conversions/calculations you need and any edge cases.
Alternative
