## How to calculate BMI?

You can calculate Body Mass Index (BMI) for adults using the formula:

BMI = weight [kg] / height2 [m]
For example, if someone weights 72 kg and is 1.70 meters tall, we can calculate the BMI this way:
BMI = 72 / 1.72
BMI = 72 / 2.89 ≈ 24.91

You can also do this with US units:
BMI = weight [lbs] / height2 [in] * 703
For example, if someone weights 150 lbs and is 5'8 tall:
BMI = 150 / 682 * 703
BMI = 150 / 4624 * 703
BMI ≈ 22.81
