Body Mass Index (BMI)

As definitions of overweight have varied widely, health experts have struggled to develop a useful definition of healthy weight. Their recommendations have evolved from weight-for-height standards to sex-specific references. The most recent proposal is to use a single number, the body mass index (BMI) that is applied to all adults. Yes, whenever we look for BMI calculator for female either BMI calculator for men, we can use this BMI formula :

BMI = weight (lb)/[height (in)] 2 × 703     or     BMI = weight (kg)/[height (m)] 2

Example:

If someone’s weight is 150 pounds and height is 5’5” (65”), the BMI is calculated as:

[150 ÷ (65) 2] × 703 = 24.96

If someone’s weight is 68 kgs and height is 165 centimeters (1.65 meters), the BMI is calculated as:

68 ÷ (1.65) 2 = 24.98

According to studies done by the National Center for Health Statistics in the United States:

  • BMI of 18.5 or less is considered underweight.
  • BMI in the range of 18.5 to 24.9 is considered normal.
  • BMI values between 25.0 and 29.0 indicate being overweight – with a BMI of 25 kg/m2 generally indicating being overweight by approximately 10%.
  • BMI of 30.0 or more indicates obesity.
  • BMI of 40.0 or more indicates morbid obesity.
