BMI Formula Explained
The calculator uses the standard BMI formula.
BMI=Height (m)2Weight (kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
How the Formula Works
The formula divides body weight by the square of height.
This helps estimate whether body weight is proportional to height.
Example BMI Calculation
Let’s calculate BMI step by step.
Example Data
- Height = 170 cm
- Weight = 70 kg
Step 1: Convert Height to Meters
170 cm = 1.70 meters
Step 2: Square the Height
1.702=2.89
Step 3: Divide Weight by Height Squared
BMI=2.8970=24.2
Final Result
- BMI = 24.2
- Category = Normal Weight
BMI Categories Explained
The calculator classifies BMI into four major categories.
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obesity |
Understanding Each BMI Category
Underweight
A BMI below 18.5 may indicate insufficient body weight.
Possible concerns:
- Nutritional deficiencies
- Low energy levels
- Weak immune system
Normal Weight
A BMI between 18.5 and 24.9 is considered healthy.
Benefits:
- Lower health risks
- Better energy levels
- Improved physical fitness
Overweight
A BMI between 25 and 29.9 indicates excess body weight.
Possible risks:
- High blood pressure
- Heart disease
- Type 2 diabetes
Obesity
A BMI over 30 may increase the risk of serious health conditions.
Potential risks include:
- Cardiovascular disease
- Sleep apnea

Healthy Weight Range Explained
The calculator also provides a healthy weight range based on your height.
It calculates:
- Minimum healthy weight
- Maximum healthy weight
The healthy range is based on BMI values between:
- 18.5
- 24.9
Formula for Healthy Weight Range
Minimum Healthy Weight
Minimum Weight=18.5×Height2
Maximum Healthy Weight
Maximum Weight=24.9×Height2
Example Healthy Weight Range
For a height of 170 cm (1.70 m):
Minimum Weight
18.5×1.702=53.5 kg
Maximum Weight
24.9×1.702=72.0 kg
Healthy Weight Range
53.5 kg – 72.0 kg
