Calculate your BMI

BMI is calculated as follows:

  • BMI = weight (kg) divided by height squared (m²)

If pounds and inches are used:

  • BMI = weight (Ibs) multiplied by 703, then divided by height squared (inches²)¹

BMI provides a method for approximating weight status and correlates with risk of disease and death due to causes associated with obesity.2

As BMI increases, the associated level of disease risk for type 2 diabetes, hypertension, and cardiovascular disease (CVD), relative to normal weight and waist circumference, also increases.3

Enter the following information and calculate your body mass index (BMI).

Height: cm
Weight: kg
Age: years

Percentile for age and gender:

The adjustment for age is a purely mathematical (not clinical) extension of the NRC adjustment, cited in Zeman, for the "healthy weight" range.
