To calculate BMI (Body Mass Index) for men, you need to use the following formula:

BMI = weight (in kilograms) / height (in meters)²

Here are the steps to calculate BMI for men:

- Measure your weight in kilograms. You can use a reliable digital scale to do this.
- Measure your height in meters. Stand straight against a wall and use a measuring tape or a stadiometer.
- Square your height by multiplying it by itself. For example, if your height is 1.8 meters, you would square it by multiplying 1.8 by 1.8, which equals 3.24.
- Divide your weight by the squared value of your height. For example, if you weigh 80 kilograms and your squared height is 3.24, you would divide 80 by 3.24, which equals 24.7.
- The resulting number is your BMI. A BMI between 18.5 and 24.9 is considered healthy for men. A BMI below 18.5 is considered underweight, while a BMI between 25 and 29.9 is considered overweight. A BMI of 30 or higher is considered obese.

Remember that BMI is not always an accurate measure of health, as it doesn’t take into account factors such as muscle mass or body composition. It’s always best to consult with a healthcare professional to interpret the results and understand their implications for your health.
