General
The calculators, converters and articles on Ali Tools Express are provided for general information and education. We work hard to make them accurate, cite our sources and test our formulas, but we cannot guarantee that every result is correct, complete or suitable for your situation. Results depend on the values you enter and on the assumptions listed on each page.
Health and medical
Health tools, such as the BMI calculator, are not medical advice. They do not diagnose, treat or prevent any condition and do not replace a consultation with a doctor, nurse, dietitian or other qualified health professional. Never ignore professional advice or delay seeking it because of something you read or calculated on this site. If you think you have a medical emergency, contact your local emergency number immediately.
Financial
Finance tools, such as the mortgage calculator, are educational and give estimates only. They are not financial, investment, tax or legal advice and are not an offer of credit. Actual payments, rates and costs depend on your lender, your contract, fees, taxes and local rules. Confirm any figures with your lender or a licensed financial adviser before making decisions.
Construction and engineering
Construction tools estimate material quantities and costs. They do not replace structural design, engineering calculations, building codes or permits. Load-bearing and regulated work must be designed or checked by a qualified professional.
External links
We link to external sources so you can check our information. We do not control those sites and are not responsible for their content.
Corrections
If you believe a result or statement is wrong, please contact us. We review every report and correct confirmed errors promptly.
