BMI Formula Explained
The BMI formula is based on weight and height.
BMI Formula
BMI=Height(m)2Weight(kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
How the Recommended Weight Range Is Calculated
The healthy weight range is based on a normal BMI between 18.5 and 24.9.
Minimum Healthy Weight
Minimum Weight=18.5×Height2
Maximum Healthy Weight
Maximum Weight=24.9×Height2
These formulas help estimate the healthy weight range for your height.
BMI Categories Explained
Here are the standard BMI categories used worldwide:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30 and Above | Obese |
Example BMI Calculation
Let’s understand the process with a practical example.
Example Details
- Height: 170 cm
- Weight: 70 kg
Step 1: Convert Height to Meters
170 cm = 1.70 meters
Step 2: Square the Height
1.70 × 1.70 = 2.89
Step 3: Apply BMI Formula
BMI = 70 ÷ 2.89 = 24.2
Result
- BMI: 24.2
- Category: Normal Weight
Recommended Weight Range Example
For a height of 170 cm:
Minimum Healthy Weight
18.5 × 2.89 = 53.5 kg
Maximum Healthy Weight
24.9 × 2.89 = 72.0 kg
Healthy Weight Range
53.5 kg – 72.0 kg
