Index Body Mass Calculator
An Index Body Mass Calculator is a health and fitness tool used to calculate Body Mass Index (BMI), which helps determine whether a person’s body weight is healthy according to their height. It provides a simple index value that reflects body weight status and helps users understand their overall health condition.
This calculator is widely used for fitness tracking, weight management, health awareness, and lifestyle planning. It gives quick results and helps users identify whether they are underweight, normal, overweight, or obese.
The Index Body Mass Calculator is suitable for men and women of all ages who want to monitor their body health easily.
What Is Body Mass Index (BMI)?
Body Mass Index (BMI) is a numerical value calculated using height and weight to estimate body fat levels and weight status.
The standard BMI formula is:
Weight (kg) ÷ Height² (m²)
Or:
Weight (lb) × 703 ÷ Height² (in²)
The result is called the BMI index, which is compared with standard categories to determine health status.
BMI Index Categories
Underweight
BMI below 18.5
This indicates low body weight and possible nutritional deficiency.
Normal Weight
BMI between 18.5 and 24.9
This is considered a healthy and balanced weight range.
Overweight
BMI between 25 and 29.9
This indicates extra body weight that may need attention.
Obesity
BMI 30 and above
This indicates high body weight and increased health risks.
