If you are concerned about your health and weight, you have undoubtedly heard of or read about BMI. BMI is short for Body Mass Index. A BMI calculator can help you find it based on height and weight to show body “fatness” or obesity.

BMI is relatively easy to determine (especially when using our calculator), provides a standardized result, and is simple to use and understand. The calculation works best for those over 18 years of age and is the same for men and women. You need your height in feet and inches and your weight in pounds.

What Is BMI Used For?

 Your calculated BMI is often used to screen for body mass/weight categories that suggest health problems, like obesity. Remember that your BMI does not measure your body fatness (body fat percentage) or your health or fitness. Physicians often use BMI to show whether a patient is overweight, underweight, or healthy body weight. Both the Centers for Disease Control (CDC) and the World Health Organization (WHO) use the results of the BMI index to determine risks for malnutrition or obesity.

Understanding Your BMI

Once you calculate your BMI, determine which category you are in:

  • Underweight: A BMI below 18.5 shows malnourishment or a need to increase calorie intake.
  • Average weight: Your BMI is between 18.5 and 24.9, a healthy weight ratio.
  • Overweight: Your overweight BMI is between 25 and 29.9, which may increase your risk of cardiovascular disease.
  • Obese: Your BMI is above 30, suggesting you may be at an increased risk for diseases and health conditions, including cardiovascular disease, high blood pressure (Hypertension), Type 2 diabetes, and breathing problems.

How The BMI Calculator Works

You can use this formula to calculate your BMI if you are a math whiz with a calculator. Convert your weight to pounds and inches and use this formula: [weight / (height x height)] x 703. Use our calculator if you are NOT a math wiz or like simple, quick results!

How Calculating Your BMI Can Help You Reach Your Health And Fitness Goals

Knowing your BMI and the corresponding category you fall into, such as underweight, average weight, and overweight, has clinical significance and is a valuable measure of body weight and mass. The higher your number, the higher your body fat and the risks for chronic health problems, including:

  • Cardiovascular disease, heart attack, and stroke.
  • Hypertension (high blood pressure).
  • Type 2 diabetes. **
  • Arthritis and sleep apnea.

Aside from genetics and family history, obesity (as shown by your BMI) is the most influential factor in determining your risk of developing type 2 diabetes. Those who fall into the obese category are 80% more likely to develop type 2 diabetes, especially those who accumulate excess body fat around their waist.

Why is it essential to calculate your BMI for your health?

The BMI determines whether you are overweight, average, or obese. Your health is paradise if you are not in the usual weight range. For example, assume you have a BMI of 17.5. You are underweight if this is the case. Being underweight makes you more susceptible to illnesses since it shows a weakened immune system. Later in adulthood, you may develop osteoporosis or become anemic.

However, if you are overweight, obese, or extremely fat, your risk of getting different illnesses rises as your BMI increases. High blood pressure, type 2 diabetes, high cholesterol, coronary artery disease, stroke, and other illnesses have become increasingly common.

What is the average BMI for adults and children?

BMI is measured in children, similar to adults, but the healthy and unhealthy limits are established differently. We deem children underweight if their BMI falls below the 5th percentile. We defined obesity as a BMI number more than the 95th percentile. A score between the 85th and 95th percentile is overweight, whereas a value between the 5th and 85th is average.


When should you visit a doctor?

If your BMI exceeds the usual range, check yourself every six months to a year. The more your BMI deviates from the normal range, 18.5 to 25, the greater your risk.

You should visit a doctor right away if you are extremely underweight or even on the verge of being obese. Unfortunately, because of the limited scope of a BMI score, it’s impossible to determine the particular state of your health for the rest of the measurements. Therefore, they are impersonal and should never substitute medical advice.

Advantages of using BMI Calculator

Accurate Measurements –

The BMI works effectively for what it does: assess obesity rates in a population. Looking at BMI levels allows researchers to get a fair sense of how rates of overweight and obesity vary over time or across groups since it’s a generic measure of obesity that will work for most individuals.

In addition, because it’s a straightforward method to assess obesity in a community, it makes it easier for health researchers to collect data to study the obesity pandemic or, for example, how dietary habits influence obesity risk in large groups.

Informs Doctor –

A healthy BMI may reduce a patient’s risk of chronic diseases like heart disease, anorexia, or diabetes. As a result, they widely used it as a diagnostic tool. In addition, since the safety of certain operations frequently depends on whether a person’s BMI is within a healthy range, surgeons will use it to evaluate patients for treatment.

Specific Goal –

The BMI isn’t the most precise measurement available. It doesn’t include muscle mass, for example, or any other variables that may lead to someone having an abnormal weight. It is, however, an aim.

You may deceive yourself by looking healthy in the mirror. You may ask friends and family members whether you are overweight or underweight. They may claim that everything is OK because they lack knowledge and a desire to protect their emotions.

Your BMI will not lie to you. Instead, it will inform you if you are at a healthy weight, which should serve as an excellent reminder to prioritize your health and fitness. However, you should only use BMI to assess your health since it isn’t very accurate. You will require a more comprehensive, holistic strategy.
