How we worked it out

Updated as you change the numbers.

  1. Height = 1.778 m; weight = 77.11 kg.
  2. BMI = weight ÷ height² = 77.11 ÷ 1.778² = 24.4.

Method and assumptions

BMI is weight in kilograms divided by height in meters squared (in US units, 703 × pounds ÷ inches²). The adult categories are the CDC’s: under 18.5 underweight, 18.5 to under 25 healthy, 25 to under 30 overweight, and 30 or more obesity. The healthy weight range is the weight that gives a BMI of 18.5 to 24.9 at your height.

Questions
