Short version: the calculators are free and provided as they are, the results are estimates from published formulas, and they are not a substitute for a doctor, dietitian or coach.
Using the calculators
- The calculators are free for personal and commercial use.
- Results are estimates for general education. Read the Health disclaimer before relying on any of them.
- The calculators and texts are provided "as is", without a guarantee that they'll always work, be error-free or suit a particular purpose.
Your numbers
Everything you type is processed in your browser. Links you copy carry your numbers after the # sign, which browsers don't send to the server. If you tick "Remember my details on this device", they are kept in this browser only. See Privacy.
Sources and names
Formulas and reference values are credited to their authors and publishers, linked on each page. Names of organizations are used only to say where a formula or value comes from; FitMathHub has no connection with them.
Problems
If a result or a text is wrong, or something on this site infringes your rights, use the contact form and choose "Mistake or bug".
