Frequently Asked Questions
What does BMI stand for?
Body Mass Index – it is a simple ratio of your weight to your height that helps classify whether you are underweight, normal, overweight, or obese.
How accurate is BMI?
BMI is a useful screening tool for most adults, but it does not measure muscle vs fat directly. Athletes with high muscle mass may show a high BMI despite being healthy.
Can I use metric units?
Yes – enter your weight in kilograms and height in centimeters. The calculator handles the conversion for you.
What is a healthy BMI range?
A BMI of 18.5 to 24.9 is considered normal for most adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Is my health data stored anywhere?
No. The BMI calculation runs entirely in your browser – we never see or store your weight or height.
