BAI Calculator with BMI Comparison
Body Adiposity Index Formula
BAI = ( HC / (HM )1.5) – 18
BMI = WK / HM2
- BAI = Body Adiposity Index
- HC = Hip Circumference in Centimeter
- BMI = Body Mass Index
- WK = Weight in Kilogram
- HM = Height in Meter
What is BMI? – Body Mass Index
The BMI calculator uses your weight and height to calculate your body mass index. In the 1830s, Belgian sociologist and statistician Lambert Adolphe Jacques Quetelet developed the BMI concert based on social psychology. When you calculate your BMI, you will be able to determine whether you need to work on your body to lose or gain weight. Furthermore, people who struggle with being overweight or underweight are frequently subjected to weight bias and stigma from others, which can lead to low self-esteem, shame, or guilt, which can lead to a variety of psychological and physiological problems.
What is the normal BMI range?
BMI is used to determine how much of our weight is above the normal weight for our height. The Normal BMI ranges from 18.5 to 25.
A person with a BMI less than 18.5 is considered underweight by the World Health Organization (WHO). It could indicate that the person has eating problems, malnutrition, decreased immune function, fertility issues caused by irregular menstrual cycles, or all of the above.
When a person’s BMI is between 25 and 30, they are considered overweight.
A person over the age of 30 is considered obese and is at a higher risk of developing some of the more severe diseases associated with obesity.
Obese people are more likely to develop heart disease and stroke, high blood pressure, diabetes, certain cancers, gallbladder disease and gallstones, osteoarthritis, and other problems.
How to calculate BMI?
The BMI is calculated using the metric system by dividing weight in kilograms by height in meters squared.
For example: Weight: 78kg, Height = 175 cm (1.75m)
The following formula is used for the weight (lb) and height (in) in the second formula.
Calculate your BMI by multiplying your weight in pounds (lbs) by your height in inches (in) squared by 703.
Example: Weight = 155 lbs, Height = 5’5 ″ (65″)
Body Mass Index Ranges – BMI Range
We have four common weight gaps in BMI that we use.
- Underweight is defined as less than 18.5 kg/m²
- 18.5 to 25 kg/m² healthy weight
- 25 to 30 kg/m² overweight
- obese greater than 30 kg/m²
BMI Calculator For Female
According to the CDC, the average weight of an American woman aged 20 and up is 170 pounds (lbs) or 77 kg. While these figures are representative of the average, they do not reflect health. A person’s BMI, which stands for body mass index, is one of the most commonly used well-being indicators. The average BMI for women in the United States is 29.6, putting them in the “overweight” category. The following is a brief overview of the BMI range for women based on height and weight:
- 1,47m, 54,4 kg – 25 BMI
- 1,57m, 54,4 kg – 22 BMI
- 1,70m, 54,4 kg – 19 BMI
- 1.47m, 68 kg – 31 BMI
- 1,57m, 68 kg – 27 BMI
- 1,70m, 68 kg – 22 BMI
- 1,82m, 68 kg – 20 BMI
Because women are generally shorter than men (though not always), their BMI range may be slightly lower than men’s. However, the scope is not significantly different.
BMI Calculator For Male
The global average body mass index for men is:
- North America: 177.9 pounds – 80.69 kg
- Oceania, including Australia: 163.4 pounds – 74.11 kg
- Europe: 156.1 pounds – 70.8 kg
- Latin America / Caribbean: 149.7 pounds – 67.9 kg
- Africa: 133.8 pounds – 60.7 kg
- Asia: 127.2 pounds – 57.69 kg
The global average adult weight is 136.7 pounds (62kg). The average 20-year-old American weighs 197.9 pounds 89.7 kilograms, has a waist circumference of 40.2 inches, and stands just over 5 feet 9 inches (1.75 meters) tall. Men, on the other hand, are less prone to gaining fat than women, who gain fat more efficiently. The World Health Organization (WHO) recommended a waist-to-hip ratio of 0.90 for men in 2008. Men with ratios of 1.0 are at a high risk of health problems.
BMI Calculator For Teens and Kids
As previously stated, adults calculate their BMI using their body weight and height. However, because children and teenagers are still growing and developing, their BMIs are plotted as percentiles on a graph. Each value is known as the BMI percentile.
The CDC recommends that children between the ages of 2 and 20 use this type of measurement. Every time your child visits the doctor, his BMI is calculated. Following that, he is entered into statistics and graphs to see how your child develops in comparison to other children his age, height, and gender.
According to the CDC, the following is how to interpret the results:
- Underweight: less than 5th percentile
- Healthy weight: 5th percentile to less than 85th percentile
- Overweight: 85th percentile to less than 95th percentile
- Obese: equal to or greater than 95th percentile
What Is a Child’s Normal and Abnormal Body Mass Index Range?
Between the 5th and 85th percentiles, a child is considered healthy.
A child who has a BMI between 85th and 95th percentile is considered overweight. Children with percentiles greater than 95 (meaning they weigh more than 95 percent of their peers) are considered obese. Childhood obesity is exacerbated by bad habits.
What are the health consequences of obesity for adults?
Obese adults are more likely to have the following chronic conditions:
- Blood pressure is high (hypertension)
- High LDL cholesterol, low HDL cholesterol, or high triglyceride levels (dyslipidemia)
- Diabetes type 2
- Coronary artery disease
- Heart problems are a possibility.
- Life quality is poor.
- Clinical depression, anxiety, and other mental disorders are examples of mental illnesses.
- Pain in the body and difficulty with physical functioning
Immediate Health Risks of Obesity in Children
Obese children are more likely to have the following serious conditions:
- High blood pressure and cholesterol levels are both of which are risk factors for cardiovascular disease
- Risk of impaired glucose tolerance, insulin resistance, and type 2 diabetes is increased.
- Asthma and sleep apnea are examples of breathing disorders.
- Musculoskeletal discomfort and joint problems
- Gallstones, fatty liver disease, and gastroesophageal reflux (i.e., heartburn).
- Heart issues
Obesity in children is also linked to:
- Anxiety and depression are examples of psychological issues.
- Low self-esteem and self-reported low quality of life
- Bullying and stigma are examples of social issues.
What is Body Adiposity Index? – BAI
The body fat index defines total body mass as adipose tissue only. Instead of body mass index, BAI is calculated without using bodyweight (BMI). Instead, compare the size of your hips to a person’s height. According to population studies, BAI is pretty much equal to the body fat percentage for adult men and women of various nationalities. BAI is a simple method for calculating body fat percentage.
To calculate the circumference of the hips, stand upright in a relaxed position with your feet as close together as possible. The best tool for measuring the circumference of the hips is a measuring tape.
It’s surprising that adiposity can be accurately estimated without using a mechanical or electronic body weight scale. Thus, even in remote locations where only the most basic and least expensive tools (a tape measure) are available, a reliable estimate of adiposity can be obtained. While adult height remains relatively constant, the measurement of hip circumference may introduce errors in the estimation of BAI.
Let’s use a 40-year-old woman with a height of 172 cm and a hip size of 107 cm as an example. We can enter all of this information into our BAI calculator and get the result BAI = 29.43%, which is considered healthy.
Normal Body Adiposity Index
- 20-39 years old: 21% are underweight, 21-33% are healthy, 33-39% are overweight, and 39% are obese.
- 40-59 years old: 23% are underweight, 23-35% are healthy, 35-41% are overweight, and 41% are obese.
- 60-79 years old: 25% underweight, 25-38% healthy, 38-43% overweight, > 43% obese
- 20-39 years old: 8% underweight, 8-21% healthy, 21-26% overweight, > 26% obese
- 40-59 years old: 11% underweight, 11-23% healthy, 23-29% overweight, > 29% obese
- 60-79 years old: 13% underweight, 13-25% healthy, 25-31% overweight, > 31% obese
The Differences between Adiposity and Obesity
Fat and obesity both indicate the presence of extra fat in the body. Furthermore, fats and obesity identify people who are at high risk of developing health problems as a result of excess body fat. BMI, or body mass index, is commonly used to assess fat and obesity. Weight and height are used in this BMI calculation. Our BMI Calculator is also available. The trick is to divide your weight in kilograms by your height in meters squared.
For example, if you weigh 58 kg and stand 1.6 meters tall, the calculation is 58 / 1.6 x 1.6, yielding 22.65.
The body mass index distribution is as follows:
- 18.5 includes the malnourished category
- 18.5 to 25, including the standard category
- 25 to 30 fall into the category of being overweight or obese.
- Obesity is defined as being over 30.
Obesity is further classified as follows:
- Obesity class 1: a BMI between 30 and 35.
- Body mass index (BMI) is between 35 and 40.
- 3. Obesity; body mass index greater than 40. Extreme obesity or severe obesity are terms used to describe obesity.

How to calculate adiposity?
(HC / (HM)1.5) – 18 BAI
Subtract 18 from your hip circumference (in cm) multiplied by your height (in m) raised to the power of 1.5.
What is the normal body adiposity index?
In the current study, BAI estimates of percent body fat ranged from 13% to 45% for men and 16% to 60% for women.
Is BAI better than BMI?
According to preliminary research, the body adiposity index is a better predictor of body fat than the body mass index.
What is adiposity rebound?
The adiposity rebound is the second increase in BMI between 3 and 7 years. Adiposity rebound at a young age is a risk factor for later obesity.
