A smart bmi calculator helps to calculate body mass index value and corresponding weight status. This calculator allows you to compute bmi for men, women, teen, and Childs. Use this calculator to know in which category your body mass index falls, it can be normal, underweight, overweight, or obese. You can enter your weight either in pounds (lbs) or kilograms (kg), and height in feet and inches or centimeters into this calculator for calculations.
Give a read to this post to understand bmi formula, chart, scale, range, classification for men and women (adult), and child and teen, and much more.
A body mass index is referred to as a measurement of leanness or corpulence that dervived from the mass (weight) and height of a person. Remember that this number does not measure body fat directly, however, it is moderately correlated with more direct measures of body fat. It is defined as body mass divided by the square of the body height, and is universally expressed in units of \(kg/m^2\), resulting from mass in kilograms and height in metres. BMI calculation is considered to determine whether a person is underweight, healthy weight, overweight or obese.
Remember that bmi ranges may vary depends on your exercise regime. The more you gain weight more will be the body mass index, but it doesn’t mean that you are obese it may be because of high muscle also.
Let’s look at the formula:
For Pounds & Inches:
$$ BMI = Weight (lb) / (Height (in))² \times 703 $$
When you considering English measurements or the above bmi equation, pounds should be divided by inches squared. And then, this should be multiplied by 703 to convert from lbs/inches² kg/m².
For Kilograms and Meters (or Centimeters):
$$ BMI = \frac {Weight (kg)}{Height (m)^2} = \frac {m}{h^2} $$
where;
\(m = mass (in kilograms)\)
\(h = height (in meters)\)
The above equation is demonstrated weight in \(kg\) divided by height in meters squared. If your height has measured in centimeters \((cm)\), then all you need to divide it by \(100\) to convert this to meters \((m)\).
Our calculator also uses the above formulas to evaluating body mass index.
Look’s at the given examples for better understanding:
Example:
What is my bmi, if:
Let’s put the value into the English formula:
\(BMI = 150 / (65)^2 \times 703 = 24.96\)
Example:
Whats my bmi, if:
Now, simply add the values into the metric formula:
\(BMI = \frac {68}{1.65^2} = 24.98\)
In general, once you determine your Body Mass Index measurement, you can easily find out if you’re at the health related risk. Our adult bmi calculator for male and female also uses the same formula to calculate body mass index for men and women.
Our calculator categorized into the four main population groups: men and women (adult), kids and teenagers. This body mass index calculator works as:
For adults 20 years old and older, Body Mass Index is interpreted by using standard weight status categories. Experts depicted that the bmi scale is something that will place you in one of six categories. These categories for BMI are the same for adult men and women of all body types and ages. Now, look at the given chart!
| Classification | Body Mass Index Score |
|---|---|
| Underweight | less than 18.5 |
| Normal Weight | 18.5 – 24.9 |
| Overweight | 25 – 29.9 |
| Obesity (Class 1) | 30 – 34.9 |
| Obesity (Class 2) | 35 – 39.9 |
| Extreme Obesity (Class 3) | 40+ |
A lean Body Mass Index can refer to as your weight maybe too low. Remember that the lower your body mass range the greater the health risks become!
Remember that individuals who have a BMI between 18.5 to 24.9 possess the ideal amount of body weight.
Remember that such an overweight range increased the risk for a variety of illnesses. Recent studies found an increased rate of diabetes, blood pressure, and heart disease was recorded at 27.8 for men and 27.3 for women. So, try the above body mass index calculator for women and men to find the your normal range! Also, once you know you are overweight, consult to your health care provider!
People within this range are prone to a physically unhealthy condition. Ideally, to reach bmi healthy range, you ought to consult your health care provider and consider reducing your weight by 5% to 10%. This weight reduction is good to reach your ideal bmi for adult men and women.
If you fall within this range, then experts depict that the risk of weight-related health problems and even death, is severe. So, immediately consult your MEDICAL PRO for optimal weight range.
Studies depicted that if an individual have BMI of 40+, it indicates that he/she have an extremely high risk of weight-related disease and even premature death. So, consult to Doctor to get recommendations according to your body mass index ranges!
Remember That!
To lower your BMI, here you need to stick to slow weight loss process, means 1 to 2 pounds per week, it is said to be as the safest way to reduce excess flab. Studies found that rapid weight loss can cause you to reduce muscle rather than fat. Apart from it, your chances of developing other health related problems increases that include gallstones and nutrient deficiencies. You ought to make legitimate long-term changes in your eating and stick to physical activities to reach your weight loss goals!
It doesn’t matter whether you’re trying to reduce or maintain your weight; you should have to improve your eating habits.
You have to reduce fat intake, and avoid all the dairy products and soft (soda) drinks. Simply, stick to at least 30 minutes physical activity a day and eat healthy to reach healthy BMI range (normal weight).
If you’re overweight with a Body Mass Index over 25kg/m2 and physically inactive, you may develop:
If you’re underweight, you may be malnourished and develop:
Body Mass Index for children and teens is referred to as age-and sex-specific. Remember that the calculation for children and teens results in BMI percentile.
Try bmi percentile calculator that tells in which percentile category your teens and children falls to CDC growth charts. Remember that the BMI ranges will remain the same for adults (women and men) throughout their life, but these figures are varying in children as kids are still at growing stage & do so at different rates.
Let’s take a look at this bmi graph to get a proper idea about percentiles:
Want to know bmi for adult men and women, kids, and teenagers, all you need to plug-in the values into the body mass index calculator, it tells yin which weight category you fall in.

Once bmi is calculated corresponding to teens and child age, it is expressed as “Percentile”, it does not matter either it is obtained from bmi percentile graph or calculator for kids and teens. These percentiles are measure that is expressed a kid’s bmi relative to U.S children; they are participated in the national surveys from 1963-65 to 1988-94. Optimistic studies depict that height and weight change during the growth and development as they both are related to body fatness. Consequently, a child’s body mass index should be interpreted relative to the other children of the same age and gender.
Let’s take a look at the bmi-for-age percentile growth chart:
| Weight Status Category | Percentile Range |
|---|---|
| Underweight | Less than the 5th percentile |
| Normal or Healthy Weight | 5th percentile to less than the 85th percentile |
| Overweight | 85th to less than the 95th percentile |
| Obese | Equal to or greater than the 95th percentile |
BMI is said to be a useful tool for determining healthful weight, but experts have depicted uncertainty about it’s reliability. Remember that when it comes to analyze body fat, BMI is not an accurate measure!
You can take a look at above CDC bmi interpretation chart or use the above calculation to find the normal range.
The BMI measurements are varying in every woman, use the above calculator to know yours!
The Ponderal Index Corpulence Index is said to be a measure of a leanness of an individual that is calculated as relationship between mass and height. In 1921, by Swiss physician Fritz Rohrer, it was the first proposed as the “Corpulence measure” and also known as Rohrer’s Index.
The first thing is that there is no any specific figure of good bmi, everyone has different ranges! Simply, plug-in the values into the above calculator know your ideal or healthy range!
Optimistic studies reveal that having an unhealthy BMI is associated with the health problems linked with obesity. For better and optimal health goals, you should consult to doctor.
Remember that maintaining a healthy BMI takes some work, stick to the following steps, it doesn’t matter whether you’re a starter or on the way:
If your BMI score is outside of a healthy range, then it’s time to call a your health care provider. Also, you may need to consult to your dietician to achieve your health goals.
