Understanding Your BMI Results
Once you get your score, it is important to know what the numbers mean. According to the World Health Organization (WHO), the standard weight status categories are:
- Underweight: BMI is less than 18.5
- Normal Weight: BMI is between 18.5 and 24.9
- Overweight: BMI is between 25 and 29.9
- Obese: BMI is 30 or greater
While BMI is a useful screening tool, please remember it does not directly measure body fat. It is always a good idea to consult with a professional for a deeper health analysis.

How is BMI Calculated? (The Formula)
The logic behind our tool is based on a simple mathematical formula:
- Metric Units: $BMI = \frac{weight (kg)}{height (m)^2}$
- Imperial Units: $BMI = 703 \times \frac{weight (lb)}{height (in)^2}$
Our tool handles these calculations automatically, including the unit conversions, so you don't have to worry about the math.
Frequently Asked Questions (FAQs)
1. Is the BMI calculator the same for men and women?
Yes, the basic BMI formula is the same for adult men and women. However, the interpretation of body fatness might vary slightly based on muscle mass and body type.
2. Is BMI accurate for athletes?
BMI can sometimes overestimate body fat in athletes or individuals with high muscle mass because muscle weighs more than fat. In such cases, BMI should be used alongside other health metrics.
3. Does this tool store my data?
No. At ToolsHQ, your privacy is our priority. Your inputs are used only for the current calculation and are not saved.
4. What is a "Healthy" BMI?
