BMI Calculator

Enter your weight and height and select the units.



Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is used to assess whether a person is underweight, normal weight, overweight, or obese. BMI Calculator can also help determine the risk of developing certain health problems, such as diabetes, heart disease, and high blood pressure.

However, BMI is not a perfect indicator of body fatness or health. It does not take into account factors such as muscle mass, bone density, age, gender, and ethnicity. Therefore, some people may have a high or low BMI but still be healthy or unhealthy.

For example, athletes and bodybuilders may have a high BMI due to their large muscle mass, but they are not considered obese. On the other hand, older adults and people with disabilities may have a low BMI due to their low muscle mass, but they may have excess body fat.

Therefore, BMI should be used as a screening tool rather than a diagnostic tool. It should be interpreted along with other measurements and assessments, such as waist circumference, body fat percentage, blood pressure, blood sugar, cholesterol levels, and physical activity.

How to Calculate Your BMI

There are two ways to calculate your BMI: using standard or metric units.

Using Standard Units

To calculate your BMI using standard units (feet, inches, and pounds), follow these steps:

  1. Measure your height in feet and inches.
  2. Measure your weight in pounds.
  3. Multiply your weight by 703.
  4. Divide the result by your height in inches.
  5. Divide the result by your height in inches again.

The final number is your BMI.

For example, if you are 5 feet 10 inches tall and weigh 180 pounds, your BMI is:

180 x 703 / 70 / 70 = 25.8

Using Metric Units

To calculate your BMI using metric units (meters and kilograms), follow these steps:

  1. Measure your height in meters.
  2. Measure your weight in kilograms.
  3. Divide your weight by your height in meters.
  4. Divide the result by your height in meters again.

The final number is your BMI.

For example, if you are 1.78 meters tall and weigh 82 kilograms, your BMI is:

82 / 1.78 / 1.78 = 25.9

What Your BMI Means

According to the Centers for Disease Control and Prevention (CDC), the following are the standard BMI categories for adults 20 years and older:

  • Underweight: BMI below 18.5
  • Normal weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI of 30 or higher

However, these categories may vary depending on the source and the purpose of the calculation. For example, the World Health Organization (WHO) uses slightly different cut-off points for some regions.

Moreover, some organizations have specific BMI standards for certain groups of people, such as the U.S. Army.

Calculate Your BMI Using Inches and Kilograms

To calculate your BMI using inches and kilograms, you need to convert your height in inches to meters and then use the metric BMI formula.

To convert your height in inches to meters, you need to multiply it by 0.0254. For example, if your height is 71 inches, your height in meters is:

71 x 0.0254 = 1.8034

Then, you need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)] 2

For example, if your weight is 70 kg and your height is 1.8034 m, your BMI is:

BMI = 70 / (1.8034 x 1.8034)

BMI = 70 / 3.252

BMI = 21.52

Calculate Your BMI Using Feet and Kilograms

To calculate your BMI using feet and kilograms, you need to convert your height in feet to meters and then use the metric BMI formula.

To convert your height in feet to meters, you need to multiply it by 0.3048. For example, if your height is 5 feet 10 inches, you need to add the inches to the feet and then multiply by 0.3048. Your height in meters is:

(5 x 12 + 10) x 0.3048 = 1.778

Then, you need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)] 2

For example, if your weight is 75 kg and your height is 1.778 m, your BMI is:

BMI = 75 / (1.778 x 1.778)

BMI = 75 / 3.161

BMI = 23.72

Calculate Your BMI Using Meters and Kilograms

To calculate your BMI using meters and kilograms, you just need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)] 2

For example, if your weight is 80 kg and your height is 1.8 m, your BMI is:

BMI = 80 / (1.8 x 1.8)

BMI = 80 / 3.24

BMI = 24.69

How to Calculate Your BMI Using Centimeters and Kilograms

To calculate your BMI using centimeters and kilograms, you need to convert your height in centimeters to meters and then use the metric BMI formula.

To convert your height in centimeters to meters, you need to divide it by 100. For example, if your height is 180 cm, your height in meters is:

180 / 100 = 1.8

Then, you need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)] 2

For example, if your weight is 85 kg and your height is 1.8 m, your BMI is:

BMI = 85 / (1.8 x 1.8)

BMI = 85 / 3.24

BMI = 26.23

Calculate Your BMI Using Inches and Pounds

To calculate your BMI using inches and pounds, you need to use the imperial BMI formula, which is:

BMI = weight (lbs) x 703 / [height (in)]2

For example, if your weight is 180 lbs and your height is 71 inches, your BMI is:

BMI = 180 x 703 / (71 x 71)

BMI = 126540 / 5041

BMI = 25.09

Calculate Your BMI Using Feet and Pounds

To calculate your BMI using feet and pounds, you need to convert your height in feet to inches and then use the imperial BMI formula.

To convert your height in feet to inches, you need to multiply it by 12. For example, if your height is 6 feet 2 inches, you need to add the inches to the feet and then multiply by 12. Your height in inches is:

(6 x 12 + 2) = 74

Then, you need to use the imperial BMI formula, which is:

BMI = weight (lbs) x 703 / [height (in)]2

For example, if your weight is 190 lbs and your height is 74 inches, your BMI is:

BMI = 190 x 703 / (74 x 74)

BMI = 133570 / 5476

BMI = 24.39

How to Calculate Your BMI Using Meters and Pounds

To calculate your BMI using meters and pounds, you need to convert your weight in pounds to kilograms and then use the metric BMI formula.

To convert your weight in pounds to kilograms, you need to divide it by 2.205. For example, if your weight is 200 lbs, your weight in kilograms is:

200 / 2.205 = 90.7

Then, you need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)]2

For example, if your weight is 90.7 kg and your height is 1.85 m, your BMI is:

BMI = 90.7 / (1.85 x 1.85)

BMI = 90.7 / 3.4225

BMI = 26.49

Calculate Your BMI Using Centimeters and Pounds

To calculate your BMI using centimeters and pounds, you need to convert your height in centimeters to meters and your weight in pounds to kilograms and then use the metric BMI formula.

To convert your height in centimeters to meters, you need to divide it by 100. For example, if your height is 180 cm, your height in meters is:

180 / 100 = 1.8

Then, you need to convert your weight in pounds to kilograms, you need to divide it by 2.205. For example, if your weight is 165 lbs, your weight in kilograms is:

165 / 2.205 = 74.83

Then, you need to use the metric BMI formula, which is:

BMI = weight (kg) / [height (m)]2

For example, if your weight is 74.83 kg and your height is 1.8 m, your BMI is:

BMI = 74.83 / (1.8 x 1.8)

BMI = 74.83 / 3.24

BMI = 23.09

BMI Standards for the U.S. Army

The U.S. Army has its own body fat standards that are based on the Department of Defense (DoD) goal of 18% body fat for males and 26% body fat for females. These standards are used to determine whether a person is eligible to join or stay in the Army.

The Army uses a formula to estimate body fat percentage based on height, neck circumference, waist circumference (for males), and hip circumference (for females). The formula is different for males and females.

To measure these circumferences accurately, the subject should be standing upright with arms at rest on both sides. The neck should be measured at a point just below the larynx (Adam’s apple), and the waist should be measured either at the point of minimum circumference or close to the navel (belly button). The hip should be measured at its widest point.

The Army also has different body fat standards depending on the age and gender of the person. The following are the maximum allowable body fat percentages for the U.S. Army:

  • Age 17 to 20: 20% for males, 30% for females
  • Age 21 to 27: 22% for males, 32% for females
  • Age 28 to 39: 24% for males, 34% for females
  • Age over 40: 26% for males, 36% for females

These standards are different from the maximum allowable body fat percentages for military service candidates, which are:

  • Age 17 to 20: 24% for males, 30% for females
  • Age 21 to 27: 26% for males, 32% for females
  • Age 28 to 39: 28% for males, 34% for females
  • Age over 40: 30% for males, 36% for females

If a person exceeds the body fat standards for their age and gender, they may be disqualified from joining or staying in the Army. They may also be subject to a mandatory weight loss program and administrative sanctions.

Therefore, it is important for anyone who wants to join or serve in the Army to maintain a healthy body weight and body fat percentage. This can be achieved by following a balanced diet and a regular exercise routine.

How to Use a BMI Calculator for the Army

A BMI calculator can be a useful tool to estimate your body fat percentage and see if you meet the Army standards. However, you should keep in mind that BMI is not a direct measure of body fat and it may not be accurate for everyone.

To use a BMI calculator for the Army, you need to enter your height and weight using standard or metric units. The calculator will then compute your BMI and compare it with the standard BMI categories.

However, these categories are not the same as the Army body fat standards. Therefore, you need to use another calculator or formula to estimate your body fat percentage based on your BMI and other factors.

One such calculator is the Army Body Fat Calculator, which uses a formula derived from the Department of Defense Instruction (DoDI) Number 1308.3. This calculator requires you to enter your height, weight, neck circumference, waist circumference (for males), and hip circumference (for females). It will then calculate your body fat percentage and show you if you are within the Army standards.

Another such calculator is the Body Fat Percentage Calculator, which uses a formula developed by the U.S. Navy. This calculator requires you to enter your height, weight, neck circumference, waist circumference (for both males and females), and hip circumference (for females). It will then calculate your body fat percentage and show you if you are within the DoD goal.

Both calculators are based on empirical data and statistical analysis, but they may not be accurate for everyone. Therefore, they should be used as a reference only and not as a substitute for professional assessment.

Conclusion

BMI is a simple and widely used measure of body fatness that can help assess health risks and fitness levels. However, it is not a perfect indicator of body fat or health, and it may not be suitable for everyone.

The U.S. Army has its own body fat standards that are based on the DoD goal of 18% body fat for males and 26% body fat for females. These standards are used to determine whether a person is eligible to join or stay in the Army.

A BMI calculator can be a helpful tool to estimate your body fat percentage and see if you meet the Army standards. However, you should also use another calculator or formula that takes into account other factors such as neck, waist, and hip circumferences.

Maintaining a healthy body weight and body fat percentage is important for anyone who wants to join or serve in the Army. It can improve physical performance, reduce health risks, and enhance morale and self-esteem.
