BMI (body mass index) is an indicator that specifies the healthiness of your body weight. It is a primarily accepted worldwide criterion for assessing healthy body weight. It compares your body weight to your body height. Irrespective of gender, adults can compute their BMI by dividing weight (kg) by the square of height(meters). You can also use our BMI calculator. If your calculated BMI is between 18.5 to 24.9, you have a normal healthy body weight. Read the benefits of healthy body weight below.

What is an unhealthy body weight?
If your computed BMI is less than 18.5 (underweight) or more than 24.9 (overweight), your weight is unhealthy. An unhealthy weight, especially in the BMI range of obesity (more than 29.9), puts you at risk of developing some diseases. Read the health risks of being overweight below.
Measuring weight for BMI calculation
- Calculate your precise body weight in kilograms using a weighing scale.
- Take a weighing scale. Ensure it operates flawlessly and reading on screen is zero when there is nothing on it.
- If any, make sure you remove personal accessories like a watch, mobile phone, ornaments, valet, etc.
- Preferably wear light-weighted clothes.
- Remove your shoes and step up to the weighing scale.
- Read and note your weight in kilograms.
Measuring height for BMI calculation
- Calculate your body height in meters
- Take a measuring tape and make sure its measurement start point is zero.
- Remove your shoes and stand over a flat surface.
- Keep a normal standing posture.
- Record measurement from the foot thumb to the top of the head.
- Note your height in meters.
Calculate BMI
- BMI = Weight/Squared Height (Kg/mm)
- Measure your weight in Kg. For example, 70Kg.
- Measure your height in meters and multiply it by itself. For example, 1.79m X 1.79m = 3.58 mm
- To calculate BMI, divide the weight by squared height. For example, 70/3.58=19.55 Kg/mm
- Alternatively, for an accurate result, use our BMI calculator.
BMI is not 100% useful to evaluate your health risks
BMI scale holds some limits as it cannot reckon a person’s body fat or protein composition. For example, an individual with a BMI value of 22.5 might keep high fats on the tummy and fall in the normal BMI class. But due to high fats, despite having a normal BMI value, he is at risk of developing cardiac diseases. Likewise, a gymholic person with a solid muscular build might fall in the overweight BMI category. Still, he might not be at risk of having fats or developing chronic illness.
