BMI Formula:
| 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 provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.
The calculator uses the standard BMI formula:
Where:
Explanation: BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. The result provides a numeric value that falls into specific categories indicating weight status.
Details: BMI is widely used as a screening tool to identify possible weight problems in adults. While it doesn't measure body fat directly, research has shown that BMI correlates with more direct measures of body fat.
Tips: Enter weight in kilograms and height in meters. Ensure accurate measurements for precise results. For pounds and inches, convert to metric units first (1 kg = 2.20462 lbs, 1 m = 39.3701 inches).
Q1: What are the BMI categories for adults?
A: Underweight: BMI < 18.5, Normal weight: 18.5-24.9, Overweight: 25-29.9, Obese: 30 or greater.
Q2: Is BMI accurate for everyone?
A: BMI may overestimate body fat in athletes and others with muscular build, and underestimate body fat in older persons who have lost muscle mass.
Q3: Why is BMI important for men's health?
A: For men, higher BMI is associated with increased risk of heart disease, high blood pressure, type 2 diabetes, and certain cancers.
Q4: How often should I check my BMI?
A: Regular monitoring (every 3-6 months) can help track weight management progress, but focus should be on overall health rather than just the number.
Q5: What's a healthy BMI range for men?
A: For most adult men, a BMI between 18.5 and 24.9 is considered healthy and associated with the lowest health risks.
