Found a result that looks wrong, or want a calculator we don't have? Email is the way to reach us.
Reporting a calculation error
Please include the calculator's name, the values you entered and the result you expected. Some tools, such as the BMI calculator and the length converter, keep your inputs in the page address, so copying the full URL is the quickest way to show us. Every confirmed error gets a fix and an automated test that checks it stays fixed (see how we check the math).
Suggesting a calculator
Tell us what you were trying to work out and which formula or standard you would expect it to follow. Requests that come up repeatedly are the ones we build first.
