Adult BMI Calculator – Free Body Mass Index Tool
Maintaining a healthy body weight is crucial for overall health and well-being. The Body Mass Index (BMI) is a simple and widely used method to assess whether an adult is underweight, normal weight, overweight, or obese. Our Adult BMI Calculator allows you to quickly calculate your BMI using weight and height, helping you track your health.
Why BMI Matters
- Health Indicator: BMI is a screening tool for weight-related health risks.
- Quick Assessment: Easily determine if your weight is within a healthy range.
- Tracking: Monitor changes in BMI over time to evaluate diet and exercise progress.
- Global Standard: Used by healthcare professionals worldwide as a reference.
BMI Formula
The Body Mass Index is calculated using the following formula:
BMI = Weight (kg) / [Height (m)]²
- Weight: Measured in kilograms (kg).
- Height: Measured in meters (m).
How the Adult BMI Calculator Works
- Enter your weight in kilograms or pounds.
- Enter your height in meters, centimeters, or feet/inches.
- The calculator squares your height and divides your weight by this value.
- Instantly get your BMI along with the corresponding weight category.
Step-by-Step Example
Problem: Calculate BMI for a person weighing 70 kg and 1.75 m tall.
Step 1: Square the height: 1.75 × 1.75 = 3.0625
Step 2: Divide weight by squared height: 70 ÷ 3.0625 = 22.86
Result: BMI = 22.86 → Normal weight
