| From: | To: |
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight and obesity in adults. For men, a healthy BMI range is typically considered to be between 18.5 and 24.9 kg/m².
The calculator uses the BMI formula:
Where:
Explanation: The calculator also determines the healthy weight range for men by calculating the weight that would correspond to BMI values of 18.5 (lower limit) and 24.9 (upper limit) for the entered height.
Details: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients. Maintaining a healthy BMI is associated with lower risks of various health conditions including heart disease, diabetes, and certain cancers.
Tips: Enter your weight in kilograms and height in meters. For height, you can convert from centimeters by dividing by 100 (e.g., 175 cm = 1.75 m). All values must be positive numbers.
Q1: Is BMI different for men and women?
A: The same BMI ranges apply to both men and women, though men typically have higher muscle mass which can affect interpretation.
Q2: What if my BMI is below 18.5?
A: A BMI below 18.5 is considered underweight, which may indicate nutritional deficiencies or other health issues.
Q3: What if my BMI is above 24.9?
A: A BMI of 25-29.9 is considered overweight, and 30+ is obese. Consult a healthcare provider for guidance.
Q4: Are there limitations to BMI?
A: BMI doesn't distinguish between muscle and fat, so very muscular individuals may have a high BMI without excess fat.
Q5: Should athletes use BMI?
A: Athletes with high muscle mass may want to use additional measures like body fat percentage for a more accurate assessment.
