| From: | To: |
Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple and widely used screening tool to identify weight categories that may lead to health problems.
The calculator uses the metric BMI formula:
Where:
Explanation: The formula converts height from centimeters to meters by dividing by 100, then calculates the square of height in meters, and finally divides weight by this value to get BMI in kg/m².
Details: BMI provides a quick assessment of weight status and helps identify potential health risks associated with being underweight, overweight, or obese. It's used by healthcare professionals for initial screening and population studies.
Tips: Enter weight in kilograms and height in centimeters. Use accurate measurements for best results. The calculator will provide your BMI value along with the corresponding weight category.
Q1: What are the BMI categories?
A: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obese (≥30).
Q2: Is BMI accurate for everyone?
A: BMI may not accurately reflect body fat in athletes, elderly, or those with high muscle mass as it doesn't distinguish between muscle and fat.
Q3: Can children use this calculator?
A: This calculator is for adults (20+ years). Children and teens require age and sex-specific BMI percentiles.
Q4: What's a healthy BMI range?
A: For most adults, 18.5 to 24.9 is considered healthy, but individual factors like muscle mass and body composition should be considered.
Q5: Should I rely solely on BMI for health assessment?
A: No, BMI should be used as a screening tool along with other measurements like waist circumference, body composition analysis, and overall health assessment.
