Formula and methodology
BMI = weight (kg) ÷ height² (m).
Inputs are validated and normalized before calculation. Working precision is retained until the visible output rule is applied.
Worked example
170 cm 70 kg: Height: 170 cm; Weight: 70 kg. The expected result is BMI chart value: 24.2; Healthy range begins: 53.5 kg; Overweight begins: 72.3 kg; Obesity begins: 86.7 kg.
Interpretation and limitations
- This is an adult screening lookup, not a diagnosis.
- Category boundaries do not describe body composition.
- Keep the stated units, assumptions, and population or jurisdiction with the result.
- Do not use a rounded display value as an exact input to another calculation.
