Knowing your BMI can help you better understand your current health status and make informed lifestyle decisions.
Although BMI is only one indicator of health, it can be a valuable screening tool when used alongside other information.
BMI is calculated using a simple mathematical formula that compares weight to height.
BMI = Weight (kg) ÷ Height² (m²)
Example: Weight: 70 kg · Height: 1.75 m → BMI = 70 ÷ (1.75 × 1.75) ≈ 22.86
For pounds and inches: BMI = (Weight in pounds × 703) ÷ Height² in inches
The calculator performs these calculations automatically, eliminating the need for manual math.
The following table provides commonly used BMI classifications for adults.
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Healthy Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obesity |
These ranges are general guidelines and should not replace professional medical advice.
