BMI calculator
Body mass index from height and weight.
Open toolHealth tools is a Netra Code page for people who need clear rules, not a sales script. Educational estimators only. They do not diagnose or dose medication.

Educational estimators only. They do not diagnose or dose medication.
Read this Health tools page together with the tool library and the contact details. Outbound policy pages we keep in view include Google Privacy Policy and W3C WAI when the topic is ads or access.
We update the Health tools when the product changes. We do not invent offices, reviews, or staff. Email corrections rather than posting personal data in a comment.
No. Calculators stay on their own URLs. This Health tools text is the policy or explainer layer.
Accuracy for the Health tools depends on the quality of what you type. Garbage in, garbage out still applies. If you mix units, the Health tools cannot guess your intent. Re-read the labels, then run it again.
Mobile use of the Health tools should not require pinch-zooming the buttons. If a control overflows, email the URL. Desktop and phone should show the same method for this Tools tool.
Print or PDF export is not required for the Health tools. Copy text, or download when the tool offers a file. Do not photograph the screen as your only record if the number matters later.
Language on the Health tools page is English. Formulas do not change when you translate the labels in your head. Keep the original units.
Netra Code will not add YouTube or Facebook video downloaders next to the Health tools. Social tools here are counters and drafts.
Accessibility: every Health tools field should have a visible label. Keyboard users can tab through the form. If a result is only shown as colour, that is a bug — report it.
Performance: the Health tools should feel instant for ordinary inputs. Huge files are the exception. Close other tabs if a phone runs out of memory on a merge.
Versioning: if the Health tools method changes, the page copy should say so. We would rather document a simplification than hide it.
Teaching: you can use the Health tools in a classroom as long as students know it is an estimate. Do not grade someone on a web calculator as if it were a statute.
Slug health-tools is the stable URL piece for this Health tools. Prefer that permalink in internal links so redirects stay simple.
Competitors exist. The reason to use this Health tools on Netra Code is the labelled method, the related tools, and the fact that we do not upsell a download of someone else’s video.
If you need a human, use the contact email. Include the Health tools URL and what you typed (never passwords or medical records).
A second pass on the Health tools is worth doing after you sleep on the first number. People change an input, forget they changed it, and trust a result that no longer matches the story they tell a doctor, a lender, or a client. Write the inputs down next to the Health tools output if anyone else will see it.
Netra Code keeps the Health tools on a stable permalink so guides, hubs, and the homepage can point at one URL. If you are documenting a process for a team, link that permalink rather than copying the JavaScript. When the method is updated, everyone who used the link sees the same change.
Finally, the Health tools is only useful if you understand the unit on each field. A height in centimetres is not a height in inches. A rate in percent is not a decimal. Re-read the Health tools labels every time you come back after a long break.
