⚡ Quick Answers
Minor differences (±0.1–0.2) are normal due to rounding in measurements. Larger differences may be due to different formulas or weight measured at different times. Our calculator uses the standard WHO formula: BMI = weight(kg) ÷ height²(m²).
Voice input requires Chrome or Edge and microphone permissions. Make sure you've allowed microphone access when prompted. It's not supported in Firefox or Safari on some platforms. If unavailable, simply type your measurements.
No. All calculations happen locally in your browser. Your height, weight, age, and any health measurements are never sent to our servers or shared with any third party. See our Privacy Policy for full details.
