Frequently Asked Questions
What is BMI and why is it important?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It helps screen for weight categories that may lead to health problems, though it's not diagnostic of body fatness or health.
What is a healthy BMI range?
For adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or higher is obese.
Should I use metric or imperial units?
Use whichever system you're most comfortable with. The calculator converts between systems automatically, so both give the same BMI result.
Is BMI accurate for everyone?
BMI is a screening tool, not a diagnostic tool. It doesn't account for muscle mass, bone density, or fat distribution. Athletes may have high BMI due to muscle, while older adults may have low BMI but high body fat.
