Important note
BMI is a simple reference value and is not a medical diagnosis. It does not directly measure body fat, muscle mass, or health condition. Consult a qualified professional for health decisions.
BMI Calculator How to use
Formula and logic
BMI = weight in kilograms ÷ height in meters squared. For example, 70 kg and 1.75 m gives 70 ÷ 1.75² = 22.86. BMI is a simple screening index, not a complete health assessment.
Practical examples
- 70 kg and 175 cm gives a BMI of about 22.9.
- 60 kg and 160 cm gives a BMI of about 23.4.
- 90 kg and 180 cm gives a BMI of about 27.8.
Frequently asked questions
Is BMI a medical diagnosis?
No. BMI is a quick reference and does not measure muscle mass, body fat distribution, or medical condition.
Can athletes have a high BMI?
Yes. Muscle mass can increase weight and BMI without meaning the same health risk.
Which units should I use?
Use kilograms and centimeters or meters consistently for reliable results.
Should children use adult BMI categories?
Children and teens need age- and sex-specific growth charts, so adult categories may not apply.
