how to calculate bmi

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

  1. Measure your weight in kilograms (kg) and your height in meters (m). If you don’t know your weight and height in these units, you can use a conversion calculator to convert from pounds and inches to kilograms and meters.

  2. Once you have your weight and height measurements in the correct units, calculate your BMI using the formula:

BMI = weight (kg) / height² (m²)

  1. For example, if you weigh 70 kg and your height is 1.75 meters, your BMI would be calculated as follows:

BMI = 70 / (1.75 x 1.75) = 22.86

  1. Your BMI number can then be compared to a BMI chart to determine if you are underweight, normal weight, overweight, or obese. Here are the general categories:
  • Underweight: BMI less than 18.5
  • Normal weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI 30 or higher

Keep in mind that BMI is just one measure of health and doesn’t take into account factors like muscle mass or body composition. It’s always a good idea to consult with a healthcare professional for personalized advice on maintaining a healthy weight.
