How do you calculate your BMI and what does it mean?

"The BMI is relatively reliable for assessing your weight but you may need to consult a doctor to get clarity on whether your weight is healthy. "

Your BMI indicates whether you’re a healthy weight for your height. BMI is short for “body mass index”.

BMI calculators use your height and weight to work out which weight range you’re in, underweight, healthy, overweight, or obese.

You can calculate your BMI by:

Dividing your weight in kilograms (kg) by / your height in metres (m). 

Then, divide that answer by your height again to get your BMI.
For example, if you weigh 70 kg and you’re 1.75 m tall, your BMI would be 22.9, which is in the healthy weight range.
