About BMI Calculator
Body mass index in metric or imperial, with the WHO category and a healthy weight range. Press Calculate to see the result in the results panel. Everything runs locally in your browser; nothing is uploaded. Only the current result is shown — no history or side-by-side comparison.
BMI Calculator reads "Units", "Weight (kg)", "Height (cm)", "Weight (lb)", "Height (ft)" and "Height (in)" from the form above and writes the answer into the results panel — BMI is a screening tool, not a diagnosis. It does not distinguish muscle from fat. There is no account, no upload and no server round-trip: the JavaScript on this page does the work on your own device.
How to use BMI Calculator
- Open BMI Calculator from Health & Everyday, or find it with the search box in the header.
- Fill in the fields shown above: "Units", "Weight (kg)", "Height (cm)", "Weight (lb)", "Height (ft)" and "Height (in)".
- Press Calculate. The result replaces whatever was shown before; only the current run is displayed, never two results side by side.
- Use Copy to put the result on your clipboard. A message appears only when something was actually copied.
A worked example
The form opens with these values: Weight (kg) = 72; Height (cm) = 175; Weight (lb) = 160; Height (ft) = 5. Press Calculate once to see how the output is laid out, then replace them with your own data and press again — the new result replaces the old one.
Frequently asked questions
Is what I type uploaded anywhere?
No. BMI Calculator processes "Units", "Weight (kg)", "Height (cm)", "Weight (lb)", "Height (ft)" and "Height (in)" with JavaScript inside your browser. Your inputs and the result stay on your device; Utilixo keeps no copy of them.
Can I keep several results to compare?
No. Each press of Calculate rebuilds the result from the current inputs and overwrites the previous one. To compare runs, note the earlier result down yourself.
