Ever noticed the doctors jotting down your weight and height every time you visit for a routine check-up? This data is used to calculate the Body Mass Index (BMI).

However, digitalisation has made this process easier with the BMI calculator. As a result, you can now know if you are underweight or overweight without wasting time on manual calculations.

BMI calculator is a handy tool that evaluates the Quetelet index. It calls for a user to enter his/her exact weight and height to estimate results. Based on the calculation, one can determine whether they are underweight or obese.

This evaluation also helps dieticians to plan a diet routine for their patients. Since a nutritious meal is important for physical and mental well being, knowing the exact measurement helps plan a balanced diet for weight management. Similarly, an underweight patient may be suggested to include medications and a healthy diet in their daily routine to gain weight.

Moreover, medical professionals usually employ the BMI calculation formula, which combines weight and height to determine a person's weight category.

However, these measurements can vary according to one’s age and gender. Therefore, knowing how to calculate BMI with age will help you calculate the BMI with respect to your age.

Now that we have covered the basics, let’s dig a little deeper on the subject, shall we?

A BMI calculator assesses an individual’s weight category by calculating the ratio of his/her weight to the height squared. 

That said, one must know that tall people have more tissues which makes them weigh more. Therefore, BMI results should not be the sole factor to determine your health plan. 

Technically, this calculator cannot assess body fat. The bones and muscles in the human body are way denser than fat. As a result, athletes and weightlifters have a high BMI though they do not have much body fat.

Nevertheless, the commonly used BMI weight chart is shown underneath.

The BMI calculator follows a simple formula to evaluate the results. It divides the weight (in kilogram) by the square of height (in meters).

Additionally, this calculator comes with multiple options like age and gender. This makes the computation result more accurate for individuals.

The BMI evaluation formula for men and women is as follows:

BMI = Weight/Height²

For instance, a female weighing around 70 kilograms and 5’ (1.524 meters) tall, her BMI is: 

= 70/(1.524)²

= 30.1 kg/m2

This data indicates that the person is obese. For this height and weight range, a BMI of 18.5 to 24.9 is normal. Therefore, the person needs to lose weight and bring it down by about 6 kilograms.

The BMI calculator has made calculating body mass index very easy. Just follow the simple steps below to find your BMI using this calculator.

Step 1: Select your gender from the given options: (Male/Female/Third Gender)

Step 2: Write down your age in numbers (Years) under the “Age” section.

Step 3: Change the height input units from feet (ft) and inches (in) to centimetre (cm) or vice versa before writing your height.

Step 4: Insert your height in feet (ft) and inches (in) or centimetres under the “Height” section.

Step 5: Now put your weight in kilograms (kgs) under the “Weight” section.

Step 6: Finally click on the calculate button to find your BMI.

Understanding the BMI calculator metric is useful to determine a person’s lifestyle and eating choices. Individuals who are underweight can evaluate the reason for these changes. In some instances, medical conditions like thyroid can increase or decrease body weight, which requires immediate medical attention.

It can also help one maintain a normal weight, reducing their risk of diseases like osteoarthritis, cardiovascular diseases, and type 2 diabetes, among other ailments.

Additionally, some other benefits of the BMI calculator are as follows:

• Allows easy and quick calculation with minimal data
• Removes the possibilities of errors, which are common in manual calculation
• Mobile friendly and inexpensive
• Some tools also offer suggestions regarding the normal body fat levels

As it calculates one’s BMI and compares it with his/her age, BMI chart helps understand whether this individual needs immediate medical attention. Moreover, fitness enthusiasts can use this tool to measure their fat percentage and plan an exercise routine accordingly.

In addition, overweight individuals can use this tool to determine the range of normal weight for themselves and work towards it.
