Example of BMI calculation

Answer 1

To calculate Body Mass Index (BMI), you can use the following formula:

\[ \text{BMI} = \frac{\text{weight in kilograms}}{(\text{height in meters})^2} \]

Here's an example calculation:

1. Weight: 70 kg
2. Height: 1.75 m

Now, plug the values into the formula:

\[ \text{BMI} = \frac{70}{(1.75)^2} = \frac{70}{3.0625} \approx 22.86 \]

So, the BMI for a person who weighs 70 kg and is 1.75 m tall is approximately 22.86.

BMI Categories:

• Underweight: BMI < 18.5
• Normal weight: BMI 18.5 – 24.9
• Overweight: BMI 25 – 29.9
• Obesity: BMI ≥ 30

In this example, a BMI of 22.86 falls within the "Normal weight" category.
