BMI Calculation: Healthy Weight Control

Body Mass Index (BMI) is an international standard used to determine whether a person's weight is appropriate for their height. It is one of the fastest and most practical methods to assess your general health status.

Key Terms

Fundamental concepts used in the BMI calculation process:

  • BMI (Body Mass Index): A value derived from dividing weight by the square of height.
  • Weight Categories: Classifications such as underweight, normal, overweight, or obese based on the BMI result.
  • Height (cm): Your height measured in centimeters.
  • Weight (kg): Your current weight measured in kilograms.

What Are These Terms?

Body Mass Index (BMI)

While BMI does not directly measure body fat percentage, it is a reliable indicator of the balance between height and weight. It is recognized by the World Health Organization (WHO) as a standard health screening tool.

What Do the Categories Mean?

  • Under 18.5 (Underweight): Indicates potential low immunity and may require nutritional support.
  • 18.5 - 24.9 (Normal): The healthiest and most ideal weight range for your height.
  • 25.0 - 29.9 (Overweight): A level that warrants attention as it may lead to obesity risks in the future.
  • Over 30.0 (Obese): A category indicating a high risk for cardiovascular and metabolic diseases.

How Does The Tool Work?

Calculation Logic

Our tool applies the standard BMI formula: BMI = Weight (kg) / [Height (m) * Height (m)]

For example, for someone weighing 70 kg and standing 1.75 m tall: 70 / (1.75 * 1.75) = 22.8 (Normal category)

Step-by-Step Guide

  1. Enter Height: Type in your height in centimeters (cm).
  2. Enter Weight: Input your current weight in kilograms (kg).
  3. Hit Calculate: Your BMI and category will be determined instantly.
  4. Review Status: See which health category you fall into and how close you are to the ideal range.

Real-World Examples

  • Fitness Tracking: Monitor BMI changes after muscle gain or fat loss during your fitness journey.
  • Health Checkup: Get an overview of your condition before a medical consultation.

Pro Tip: BMI may not always be accurate for athletes with high muscle mass or elderly individuals. Consult a specialist for a more comprehensive assessment.
