Frequently Asked Questions
Can I suggest a new calculator or converter?
Yes. Email us the name of the calculator or converter you would like and what you want it to work out. We read every suggestion, though we cannot promise to build all of them.
How do I report an incorrect result?
Email us the name of the calculator, the numbers you entered and the result you expected. That lets us repeat the calculation and fix any mistake we find.
Do I need an account to contact you?
No. You do not need an account or a sign-up. Just send us an email.
How long does it take to get a reply?
We aim to reply within 2 to 3 working days. A simple question is usually quicker than a request that needs us to check a calculation.
