BMI Calculator

Body Mass Index (BMI) is a number that can be calculated mathematically using inches and pounds or meters and kilograms to show body weight adjusted for height. For adults aged 20 years or older, BMI numbers slot into the following categories:

  • 18.5 = underweight
  • 18.5-24.9 = normal weight
  • 25-29.9 = overweight
  • 30-34.9 = obesity level I
  • 35-39.9 = obesity level II
  • 40+ = extreme obesity
