Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. BMI provides a reliable indicator of body fatness for most people.
The calculator uses the standard BMI formula:
Where:
Explanation: The formula divides weight by the square of height to account for the fact that weight increases with the square of height.
Details: BMI is a simple, quick screening method for weight categories that may lead to health problems. It helps identify potential weight problems for adults.
Tips: Enter weight in kilograms and height in meters. For accurate results, measure height without shoes and weight with minimal clothing.
Q1: What is a healthy BMI range?
A: For adults, 18.5 to 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: Is BMI different for women and men?
A: The same BMI ranges apply to both genders, but women tend to have more body fat than men at the same BMI.
Q3: What are BMI limitations?
A: BMI doesn't distinguish between muscle and fat, so athletes may have high BMI without excess fat. It also doesn't account for fat distribution.
Q4: How often should I check my BMI?
A: For most adults, checking every few months is sufficient unless you're actively trying to change your weight.
Q5: Is BMI accurate for pregnant women?
A: No, BMI calculations during pregnancy are not meaningful because of natural weight gain.
