Frequently Asked Questions
What is BMI?
BMI stands for Body Mass Index. It is a simple calculation using a person's height and weight to determine if their weight is healthy, underweight, overweight, or obese relative to their height.
How is BMI calculated?
The standard formula for BMI is weight in kilograms divided by height in meters squared (kg/m²). For pounds and inches, the formula is (weight in pounds / height in inches squared) x 703. Our calculator handles this math for you instantly.
Is BMI always accurate?
No. While BMI is a good general screening tool for the population, it doesn't distinguish between muscle and fat. Highly muscular athletes, like bodybuilders, may have an 'Obese' BMI while actually having very low body fat and excellent health.
