what is the equation to calculate your bmi?

The basic equation to calculate your BMI is:

• Using metric units:
  \text{BMI}=\dfrac{\text{weight in kilograms}}{(\text{height in meters})^2

• Using US units (pounds/inches):
  \text{BMI}=\dfrac{\text{weight in pounds}}{(\text{height in inches})^2}\times 703

Example: If you weigh 70 kg and are 1.70 m tall, then BMI = 70÷(1.70^2)≈24.2.
