Feedback, bug reports and calculator requests are always welcome.
Calcoolyis made for people who just need the number — and your input makes it better. Whether you've spotted something wrong, want a calculator we don't have yet, or just have a question, we'd love to hear from you.
Good things to include
- Which calculator you're writing about (a link helps).
- What you expected versus what you saw.
- Your device and browser, if it's a display issue.
