Editorial Policy

Last updated: July 11, 2026

Our goal is to provide clear, practical, and easy-to-understand calculator content for general educational use.

Calculator formulas are presented transparently, and pages are written to help users understand what the estimates mean, how to use them, and when caution is needed. We avoid presenting calorie estimates as guarantees.

When health or nutrition topics are discussed, the site uses conservative language and encourages professional consultation for medical conditions or major diet changes.

Corrections and feedback can be sent through the contact page.

Data packages and corrections

Public data pages identify the original source, data year, indicator definition, BMITDEE processing, download formats and material limitations. Descriptive differences are not presented as statistically significant unless an appropriate analysis supports that claim. Correction requests can be submitted through the Contact page; material corrections should be dated on the affected data page.

Derived reference datasets

BMITDEE labels calculated reference tables separately from observational datasets. Each derived product states its formulas, category boundaries, rounding rules, population context and limitations. Corrections can be submitted through the publisher request form.

Open-source calculations and test vectors

Developer packages publish formula names, package versions, formula versions, units, assumptions and warnings. Numeric behavior changes require tests, changelog documentation and updated public vectors. Experimental adaptive methods are labelled separately from stable deterministic formulas.

Open-source code improves auditability but does not turn calculator output into a medical measurement or clinical recommendation.
