Terms of Use

utils.appb.in provides free utility tools for general, all-ages use. By using this site you agree to these terms.

Use

These tools are provided for personal, non-commercial use. The results are provided as-is and should not be the sole basis for medical, financial, legal, or safety decisions. Always verify important calculations independently.

Content

This is a general-audience site with no age-restricted content. It is not directed at children under 13.

Accuracy

We take accuracy seriously and conversion factors are sourced from authoritative references (NIST SP 811). That said, we provide no warranty of accuracy. BMI, for example, is a screening tool and not a medical diagnosis.

This site is provided "as is" without warranties. We are not liable for any losses resulting from use of these tools.
