Body Mass Calculator
A Body Mass Calculator is a health and fitness tool used to measure Body Mass Index (BMI). It helps you understand whether your body weight is healthy according to your height. The result shows if a person is underweight, normal weight, overweight, or obese.
This tool is widely used in fitness tracking, weight management, and general health awareness. It gives a quick and simple way to check body condition without medical tests.
The Body Mass Calculator is suitable for men, women, and adults of all ages who want to monitor their health and maintain a balanced lifestyle.
How Body Mass (BMI) Works
Body Mass Index is calculated using a simple formula that compares weight with height.
The standard formulas are:
Weight (kg) ÷ Height² (m²)
Or
Weight (lb) × 703 ÷ Height² (in²)
After calculation, the result is compared with standard health ranges to determine body condition.
This makes it easy to understand whether your weight is healthy or needs adjustment.

BMI between 25 and 29.9
