How to Calculate BMI for Healthy Weight?

The Body Mass Index (BMI) is a useful method that tells you about your overweight and obesity. BMI calculates the body fat rate by using some measurements like height and weight. It also helps you to find out the risks of diseases that may happen due to the increase in body fat. Remember that if your BMI increases, the risk for certain diseases is also higher. However, it is important for you to know that BMI does not still represent the exact body fatness for a healthy weight. 

Two general formulas are given below for BMI calculation: 

 

In metric units:

BMI = \frac {Weight (kg)}{Height (m)^2} = \frac {m}{h^2}

 

In US units:

BMI = weight (lb) ÷ height2 (inches) * 703\

Or 

[weight (kg) / height (cm) / height (cm)] x 10,000

Calculating BMI is an individual’s weight in kilograms divided by the square of height in meters. By using the BMI formula, you can easily calculate Body Mass Index accurately in various units. It is noticeable that a high BMI represents high body fatness while a low BMI can indicate low body fatness. 

BMI women indicate whether they have a healthy Body Mass Index or an obese. Typically a healthy woman’s BMI lies between 18.5 and 24.9. In case a woman is pregnant or is planning for pregnancy, she can determine her recommended weight gain using her pre-pregnancy BMI (Body Mass Index).

Healthy men’s BMI scale sets their target weight range depending on their height. Generally, BMI men can be calculated with the corresponding weight rate by taking age & weight. A healthy man’ BMI within the normal weight range is between 18.5 and 24.9. Remember that a man’s ideal BMI does not alter with various health ailments.

Children’s BMI can be calculated according to the age percentile that primarily depends on the CDC (Centers for Disease Control) growth charts for children. On the other hand, calculating BMI for teenagers is based on clinical growth charts. The BMI tells about the teen’s body mass range falling into underweight, healthy weight, overweight, or obese. Using the BMI formula, a child and teenager can calculate their body weight rate and also find certain risks if they take place in them. 

Although the BMI scale can be used for both men and women it does have some limitations.
