BMI (Body Mass Index) is a measure of body fat based on height and weight. Here are the steps to calculate BMI:

- Measure your weight in kilograms (kg)
- Measure your height in meters (m)
- Square your height (multiply your height by itself)
- Divide your weight by the square of your height
- The result is your BMI

Here is the formula: BMI = weight (kg) / [height (m)]^2

For example, if your weight is 70 kg and your height is 1.75 m, the calculation would be:

BMI = 70 / (1.75)^2 BMI = 22.86

So, your BMI is 22.86, which falls within the healthy range of 18.5 to 24.9.

Here’s a more detailed explanation on how to calculate BMI step by step:

- Measure your weight in kilograms (kg). You can do this by using a weighing scale. Make sure to remove any heavy clothing or shoes before stepping on the scale to get an accurate measurement.
- Measure your height in meters (m). You can do this by standing straight against a wall and measuring your height from the floor to the top of your head using a measuring tape. Make sure to remove your shoes and stand straight while taking the measurement.
- Square your height. To do this, multiply your height by itself. For example, if your height is 1.75 meters, multiply it by itself to get 3.06.
- Divide your weight by the square of your height. Use the formula: BMI = weight (kg) / [height (m)]^2. For example, if your weight is 70 kg and your height is 1.75 m, the calculation would be:

BMI = 70 / (1.75)^2 BMI = 70 / 3.06 BMI = 22.86

- The result is your BMI. In this example, the BMI is 22.86, which falls within the healthy range of 18.5 to 24.9.

It’s important to note that while BMI is a useful tool to measure body fat, it’s not always accurate. Factors such as muscle mass, bone density, and age can affect the BMI result. Consult with a healthcare professional for a more accurate assessment of your body fat percentage.
