BMI Calculator - Body Mass Index Calculator

Enter weight and height

Using the Body Mass Index calculator is easy. Once you have entered your information into the calculator, it will compute your Body Mass Index (BMI).

Please note that the Body Mass Index is an indicative measure of your body’s condition and does not tell the whole truth.

Body Mass Index Calculator Results

The Body Mass Index calculator shows you a number based on the information you provided. Using height and weight, it can calculate how a person ranks according to the BMI index. The result roughly indicates whether a person is overweight, underweight, or of normal weight.

Keep in mind that the results from the Body Mass Index calculator may not be reliable. A shorter person may have a large amount of muscle, resulting in a high BMI index. In this situation, the person may not be overweight, even though the BMI number suggests otherwise.

The Body Mass Index Does not Tell the Whole Truth

The Body Mass Index has long been included as part of health monitoring. However, it is intended as an indicative tool and does not in any way tell the whole truth about a person’s health status. For a person with no muscles, the BMI number is more accurate, as the BMI number does not account for muscles in the equation in the same way.

Body Mass Index formula: weight / (height * height)

All bodies are different, so in addition to the Body Mass Index, many other factors should be considered.

For example, a person with no muscles may have a low Body Mass Index, but their health may not reflect this.

Conversely, a very muscular person may have a very high Body Mass Index, even if their body fat percentage is low.

The Body Mass Index can vary throughout the day, as the body tends to easily retain fluid. Eating large amounts during the day can cause weight to fluctuate by several kilograms.

If the result is measured in the morning on an empty stomach, the Body Mass Index number may be significantly lower than after a large meal in the evening.

Consult a Professional if Necessary

The Body Mass Index calculator provides you with indicative information about your weight in relation to your height. However, you know best how your body feels and what your potential health condition is.

Frequently Asked Questions about the BMI Calculator

The Body Mass Index calculator may raise questions. We have compiled some common questions and answers here.

What is a Normal BMI?

A normal BMI is 18.5 – 24.9. For example, a person who is 185 cm tall should weigh approximately 64 – 85 kg to remain within a normal BMI range.

What is the Normal Weight for 180 Cm?

Normal weight is approximately 62 – 81 kg. According to the Body Mass Index, the person would be of normal weight, but muscles, bone density, and many other factors affect the Body Mass Index reading.

What is the Ideal Body Mass Index?

The ideal Body Mass Index is 18.5 – 24.9, meaning the person’s Body Mass Index is normal. The ideal BMI, calculated as the midpoint of the normal Body Mass Index, is 21.7 in this case.

Is the Body Mass Index a Reliable Measure?

The Body Mass Index reading is indicative and can be used to measure a person’s health. However, many other factors besides weight and height affect a person’s health, so the Body Mass Index should not be relied upon as the sole measure. If you want to obtain a certain and comprehensive understanding of your health status, contact a doctor.
