What is BMI?

Body Mass Index (BMI) is a simple measurement using your weight and height to work out if your weight is healthy.

BMI Formula

BMI = weight (kg) ÷ height² (m²)

BMI Categories

  • Underweight:BMI less than 18.5
  • Normal:BMI 18.5 to 24.9
  • Overweight:BMI 25 to 29.9
  • Obese:BMI 30 or greater

Important Considerations

  • BMI is a useful measurement for most people over 18
  • Not applicable to children, pregnant women, or highly muscular athletes
  • Ethnicity can affect health risks at different BMI thresholds
  • Consider BMI alongside diet, exercise levels, and family history

How to Calculate BMI

Learn how to accurately calculate your Body Mass Index (BMI) using the standard formula.

BMI Formula

BMI = weight (kg) ÷ height² (m²)

Steps to Bmi Calculate:

  1. Convert your height to meters (if in centimeters, divide by 100)
  2. Square your height (multiply it by itself)
  3. Divide your weight in kilograms by your squared height
  4. Round the result to one decimal place

Example Bmi Calculation

For someone who is:

  • Height: 170 cm (1.7 m)
  • Weight: 70 kg

1. Height in meters = 1.7 m

2. Height squared = 1.7 × 1.7 = 2.89 m²

3. BMI = 70 ÷ 2.89 = 24.2

This BMI of 24.2 falls within the normal weight range (18.5-24.9).

Unit Conversion Tips

Height Conversion

  • • Centimeters to meters: divide by 100
  • • Inches to meters: multiply by 0.0254
  • • Feet to meters: multiply by 0.3048

Weight Conversion

  • • Pounds to kilograms: divide by 2.205
  • • Stones to kilograms: multiply by 6.35
