What is a BMI Calculator?

A BMI calculator is a tool that uses your height and weight to calculate your Body Mass Index (BMI), a screening tool that indicates whether you are underweight, normal weight, overweight, or obese.

How accurate is the BMI calculation?

Our BMI calculator uses the standard formula (weight in kg / (height in m)²) to provide an accurate BMI number. However, BMI is a screening tool and does not account for muscle mass, bone density, or overall body composition.

What is a healthy BMI score?

For most adults, a healthy BMI score is between 18.5 and 24.9. This indicates a normal weight for your height. A BMI below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is considered obese.

Understanding Your BMI Results

Body Mass Index (BMI) is a measure of body fat based on your weight in relation to your height. It is used as a screening tool to identify potential weight problems in adults.

Health Risks Associated with BMI Categories:

Underweight (Below 18.5): May indicate malnutrition, osteoporosis, or other health issues.
Normal Weight (18.5 - 24.9): Associated with the lowest risk of weight-related health problems.
Overweight (25 - 29.9): May increase risk of heart disease, high blood pressure, and type 2 diabetes.
Obese (30 or higher): Significantly increased risk of serious health conditions including heart disease, stroke, and certain cancers.

Remember that BMI is just one indicator of health. Other factors like muscle mass, bone density, and overall fitness level are also important.
