Get in touch
Use the Wezual contact page to reach the team. Please mention Wezual Calculators and the page your message concerns.
Report a calculation issue
Include the calculator name or page address, the values and units you entered, the result shown and the result you expected. A small example that reproduces the issue is usually more useful than a screenshot alone. If you used a formula, reference document or another tool to check the answer, include that information too.
Protect your information
Use sample numbers when reporting an issue. Do not send account numbers, passwords, medical records, identity documents or other sensitive information. When sharing a page address, remove any private values from its query string first.
Suggest a new calculator
Tell us what question the calculator should answer, which inputs it needs and how you would use the result. Suggestions that include the expected units and a worked example help us understand the task.
Privacy and advertising questions
Describe which privacy choice or advertising issue you want help with, along with the relevant page. You can find information about third-party advertising and browser choices in our Privacy Policy.
