Bmi Calculator

(Body Mass Index) BMI Calculator

Online BMI calculators help people to calculate their body mass index value and their corresponding weight status. It allows them to compute Body Mass Index for men, women, teens, and children. You can use this BMI calculator to know in which category your body mass falls, whether it is healthy, underweight, or overweight. 

With this BMI calculator, you can easily enter your weight in kilograms (kg) and pounds (Ibs), and your height in feet and inches or even in centimeters for the results. 

Body Mass Index (BMI): 

BMI is referred to as the measurement of corpulence and leanness that is derived from the height and weight of an individual. You need to remember that this number will not measure your body fat directly; however, it will moderately correlate with more direct measures of your body fat. It is defined as the body mass divided by the square of height and is represented by kg/m^2 in units. 

BMI calculation is considered to help people determine if they are underweight, healthy, overweight, or obese. It can ultimately save them from a variety of life-threatening health problems such as cardiovascular diseases, high blood pressure, stroke, and obesity. 

Remember that Body Mass Index (BMI) may vary depending on your age or exercise regime. The more weight you possess, the more will be your BMI, but that doesn’t mean that you are overweight, it just means you have high muscle mass. 

What is BMI Formula? 

Now, let’s take a look at the BMI formula women and men: 

ENGLISH BMI FORMULA: 

For inches and Pounds: 

BMI= Weight (Ibs) /(Height (in))^2 x 703 

According to the English measuring or the above BMI equation, pounds are divided by inches squared, and then, multiplied by 703 to convert from Ibs/inches^2 kg/m^2. 

Metric BMI Formula: 

For kilograms and Meters (or Centimeters): 

BMI= Weight (kg)/ Height (m) ^2= m/h^2

Where; 

m= mass (in kilograms) 

h= height (in meters) 

If we consider the above equation, the weight in kg is divided by height in meters squared. If you measure your height in centimeters (cm), then you have to divide it by 100 to convert this to meters (m). 

You can use our above BMI calculator to evaluate your Body Mass Index. 

How can I calculate BMI? 

Down below are some examples that will help you understand Body Mass Index calculators better: 

How to Calculate with English Measurement? 

For Example: 

What will be my BMI, if: 

• My weight is 150 Ibs 
• My height is 5’5 (65 inches) 

The English formula is: 

BMI= 150/ (65) ^2 x 703 = 24.96 

How to Calculate with Metric Measurement? 

For example: 

What will be my BMI, if: 

• My height is 165 cm (1.65 m) 
• My weight is 68 kg 

Now, just simply add the values into the metric formula and you’ll get the BMI. 

BMI= 68/ (1.65) ^2 =24.98

Generally, once you calculate your Body Mass Index, you can easily determine if you’re in the healthy range or not. Our calculator uses the same formula for both males and females.

How is BMI interpreted for Adults? 

For adults 20 years or older, our BMI calculator is interpreted by using standard weight status categories. Experts have revealed that the Body Mass Index (BMI8) scale is something that will place you in one of the given six categories. These will be the same for both adult men and women of all body sizes and ages. Now, look at the given table: 

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+

Remember that! 

Having a higher BMI can lead to many serious and life-threatening diseases. So, you must try to lower it and maintain a healthy body mass. In order to lower your Body Mass Index (BMI), you will need to stick to a slow weight loss process, meaning 1 to 2 pounds every week. You need to remember that slow and steady wins the race and this is the safest way to reduce those extra pounds. Studies have proved that rapid weight loss techniques usually lead to developing other harmful medical problems such as gallstones and nutrient deficiencies. 

You ought to make legitimate long-term changes in your routine and eating habits, and get yourself into some sporty activity in order to reach that healthy weight loss goal! 

Studies have also shown that if someone has BMI over 40, he/she is more likely to get weight-related diseases and even premature death. To prevent that, you need to reduce your fat intake and try avoiding all dairy products, and soft drinks (soda). Side by side, stick to a regular 30 minutes physical activity to maintain that healthy BMI range (normal weight. 

The Risks of Being Overweight or Physically Inactive: 

If you are overweight or obese and are physically inactive, you may develop the following health problems: 

• High Blood Pressure 
• Type 2 diabetes 
• Cardiovascular diseases (disease of heart and blood circulation) 
• Osteoarthritis 
• Breast cancer 
• Colon cancer 
• Hypertension 
• Mental health disorders such as anxiety and depression. 

The Risks of Being Underweight: 

Being underweight and malnourished can also lead to various health problems such as: 

• Digestive disease
• Respiratory disease
• Cancer 
• Osteoporosis 
• Comprised Immune Function 

Possible Limitations of BMI: 

Body Mass Index (BMI) is considered a very useful tool in terms of determining a healthful weight; however, experts have depicted some uncertainty about its reliability and its methods of publishing the calculations. You should always remember that when it comes to analyzing body fat, a BMI is not an accurate measure! 

• Body Mass Index is not something that can distinguish between the body’s water weight and muscle mass etc. 
• It measures the overall nutritional status, corresponding to relation with height and weight of an individual. Though, it doesn’t give any status about the body fat percentage of the bone muscle. 
• BMI is not specific to the sex of a person. For example, the BMI of males and females uses the same formula, however, men contain more muscle mass and females comprise more fat mass which is nowhere mentioned in the Body Mass Index (BMI) charts. 

Four methods to work out your ideal weight: 

METHOD 1: BODY MASS INDEX (BMI) 

Body Mass Index is a very common tool that can help people to determine if they have an appropriate body weight. It is a way to find out the body mass of an individual with respect to their weight. 

According to the publication by the National Institutes of Health (NIH): 

1. BMI less than 18.5 means that the individual is underweight. 
2. BMI between 18.5 and 24.9 is ideal. 
3. BMI more than 25 and till 29.9 means the person is overweight. 
4. BMI over 30 means the person is obese. 

In order to calculate your Body mass, insert the data (your weight and height) into the BMI calculator given above. 

Weight and height guide chart: 

ABOUT BMI: 

Body Mass Index is a simple method of knowing your estimated body weight with respect to your height. While it considers the person’s height into consideration, factors such as hip or waist measurements, distribution of fat, and proportion of muscle and bone mass are not taken into account while measuring BMI. 

However, these factors can also have an impact on human health. 

High-performance athletes tend to be fit and have little body fat. So, those individuals can have high BMI due to the more muscle mass in their body, but that certainly doesn’t mean they are overweight. 

Such online Body Mass Index (BMI) calculators offer a rough idea to the users as to whether they are healthy, fit, or obese.

METHOD 2: BODY FAT PERCENTAGE: 

The Body Fat Percentage of a person is the weight of that individual’s body fat, divided by their total weight. Total Body Fat includes both the storage and essential fat. 

Storage Fat: The fatty tissues of our body protect the internal organs in the abdominal region and the chest, and the body uses that fat for energy purposes. 

Essential Fat: A person requires essential fat in order to survive. It plays a key role in a wide range of body functions. For males, it is healthy to have approximately 2 to 4 percent of their body composition as essential fat, while in females; the figure is 10 to 13 (as stated by the American Council on Exercise ACE). 

Apart from these important guidelines for both men and women, the ideal total fat percentage of an individual depends on their body type and activity level. 

ACE recommends the following percentages, as it varies in males and females: 

ACTIVITY LEVEL	MALE BODY TYPE	FEMALE BODY TYPE
Athletes	6 to 13 %	14 to 20 %
Fit but non-athletes	14 to 17 %	21 to 24 %
Acceptable	18 to 25 %	25 to 31 %
Overweight	26% to 37 %	32 to 41 %
Obesity	38% or more	42% or more

A high proportion of body fat may lead to some serious medical diseases such as: 

• Diabetes
• Heart diseases
• Hugh blood pressure 
• Stroke 

Calculating the Body Fat Percentage can help to determine a person’s fitness level as it reflects that person’s body composition. Body Mass Index (BMI), on the other hand, does not distinguish between the body and muscle mass. 

METHOD 3: WAIST-TO-HIP RATIO: 

An individual’s waist-to-hip measurement can help to compare their waist size with their hips. 

According to research, it was stated that people who have more fat around their middle area are more likely to develop cardiovascular disorders and diabetes. The higher the waist measurements of a person in proportion to their hips, the greater the risk of such health problems. 

For that reason, using a waist-to-hip ratio (WHR) is also a useful tool; to calculate whether a person has a healthy weight/size or not. 

How to measure? 

1. Measure around the narrowest part of your waist, usually just above the belly button. 
2. Divide that measurement by the measurement at the widest part around your hips. 
3. For example, if your waist is 28 inches and your hips measure 36 inches, divide 28 by 36, and your waist-to-hip ratio will be 0.77. 

What does it actually mean? 

How the waist-to-hip ratio affects an individual and the risk of cardiovascular disorders in them is different for both men and women, just like it is different in BMI. That’s because both genders tends to have different body shapes and sizes. 

In Males: 

• Below 0.9 means the risk of CVD is low. 
• From 0.9 to 0.99, the risk is moderate. 
• At 1.0 or over, the risk of cardiovascular health problems is high. 

In females: 

• Below 0.8, the risk will be low. 
• From 0.8 to 0.89, the risk is considered moderate. 
• At 1.0 or over, the risk of CVD health problems is high.

However, these figures can vary depending on the population or the source to which they apply. WHR is less likely to accurately measure an individual’s total body fat percentage or their muscle-to-fat ratio. 

A study that was published back in 2013 revealed that over 1,300 people in 11 countries having a higher WHR have a higher risk of surgical and medical health complications relating to colorectal surgery. 

METHOD 4: WAIST-TO-HEIGHT RATIO: 

The Waist-to-height ratio is another great tool that helps to predict the risk of heart diseases, diabetes, and overall healthy mortality, even more effectively than BMI. 

A person whose waist measurement is less than half of their height has a lower risk of a number of various life-threatening complications. In a study that was published in 2014, researchers revealed that WtHR was a better predictor than BMI itself. 

Measure your waist-to-height ratio: 

To calculate the WtHR of a person, divide their waist size by their height. If the answer is 0.5 or less, chances are that your body weight is healthy. 

1. For example, if a woman is 5 ft. 4 tall (163 cm), she should have a waist measurement below 32 inches (81 cm). 
2. If a man is 6 ft. tall (183 cm), he should have a waist measurement below 36 inches (91 cm). 

Does being overweight lead to any medical risks? 

The greatest reason to maintain an ideal body weight is to reduce the risks of any medical problems or diseases, which are more likely to occur when a person is overweight. Such conditions include coronary artery diseases, high blood pressure, diabetes, cancer, cardiovascular disorders, and many other serious health problems. All of these medical problems contribute to an overall increase in the death rate around the world. 

 A person that has an unhealthy BMI greater than 30 may have a high risk of getting diabetes, high blood pressure rate, and fatal heart diseases. However, having a low BMI can also lead to a variety of health problems such as malnutrition, poor bone density, and body image issues. 

What steps can I follow to lose weight? 

The following steps will help you reduce unwanted body fat and lose weight: 

• Educate yourself about the risks of being overweight. 
• Decide that you want to lose the excess body weight permanently. 
• Seek professional help from your dietician or doctor. 
• Have a realistic health goal in your mind. 
• Follow up with your care team to keep yourself motivated. 
• Understand the fact that obesity is a long-term condition and can become the cause of some serious diseases in the future.
