how to calculate BMI


BMI (Body Mass Index) is a simple calculation that uses a person's height and weight to determine their level of body fat. It is a commonly used method to determine if a person is underweight, at a healthy weight, overweight, or obese. To calculate BMI, follow these steps: Step 1: Measure your height in meters or feet For example, if your height is 1.7 meters, convert it to centimeters (1.7 x 100 = 170 cm). If your height is 5 feet 5 inches, convert it to inches (5 x 12 = 60 inches) and add it to the remaining inches (5 x 12 + 5 = 65 inches). Step 2: Measure your weight in kilograms or pounds If your weight is 60 kilograms, keep it as it is. If your weight is 140 pounds, convert it to kilograms (140 ÷ 2.2 = 63.6 kg). Step 3: Calculate your BMI Use the following formula to calculate your BMI: BMI = weight (kg) ÷ height^2 (m^2). For example, if your weight is 63.6 kg and your height is 1.7 meters, your BMI would be: 63.6 ÷ (1.7)^2 = 22.02. Step 4: Interpret your results Once you have calculated your BMI, you can check the range in which it falls to determine your level of body fat. Here is a general guideline: - A BMI below 18.5 is considered underweight - A BMI between 18.5 and 24.9 is considered normal or healthy weight - A BMI between 25 and 29.9 is considered overweight - A BMI above 30 is considered obese It is important to note that while BMI can be a good indicator of body fat, it does not take into account a person's muscle mass, so it may not be an accurate measure for athletes or people with a lot of muscle mass. It is always best to consult with a healthcare professional to determine your ideal weight range and any potential health risks associated with your BMI.
