Frequently asked questions
Is this result medical advice?
No. It is a general estimate based on the values and formula shown. A qualified health professional can interpret measurements for your circumstances.
Are my entries uploaded?
No. The calculation runs in your current browser tab, and the tool does not send the values to a server.
Why might my result differ elsewhere?
Methods, rounding and reference assumptions vary. Check the selected units and inputs, then treat the result as an estimate rather than a diagnosis.
Understanding the estimate

- The result follows the method named in the tool and rounds figures for easy reading.
