Calculator Corrections
If your message is about a possible calculator issue, please include the page URL, calculator name, selected substance, value entered, result shown, and the result you expected.
For new calculator suggestions, include the unit pair, example use case, and any reference formula or standard conversion factor we should review.
Advertising and Partnerships
For advertising, sponsorship, or partnership questions, use the same email address and include a clear subject line so we can route the message properly.
Medical Advice
We cannot provide personal medical advice, diagnosis, or treatment recommendations by email. If you have questions about your own lab results, symptoms, medication dose, or medical condition, please contact your physician, pharmacist, or another qualified healthcare professional.
Response Time
We try to review messages as soon as possible. Response times may vary, but correction requests and calculator accuracy reports are prioritized.
