Example of Using the Harvard BMI Calculator
To better understand how the calculator works, here is an example:
Scenario:
- Weight: 70 kg
- Height: 170 cm
Calculation:
The BMI is calculated using the formula: BMI=Weight (kg)Height (m)2\text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}BMI=Height (m)2Weight (kg)
Step-by-Step:
- Convert height to meters: 170 cm = 1.7 m
- Apply the formula: BMI = 70 / (1.7 × 1.7) = 70 / 2.89 ≈ 24.22
Result: Your BMI is 24.22, which falls within the normal weight range.
Understanding Your BMI Results
The BMI categories are generally divided as follows:
| BMI Value | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
Knowing your BMI category helps you make informed decisions about your diet, exercise, and lifestyle habits.
